From flextime pioneer to provider of New Work solutions

Unlocking the power of numbers

New Work and work-life balance: many people view these terms as meaning flexible, self-determined work from anywhere, anytime. This concept has been around for a while now. Here at Interflex, we’ve been working to add flexibility to working time for 50 years now through technological solutions, giving millions of employees more personal responsibility – now and into the future. That’s because people are at the heart of everything we do.

We started out as a pioneer in time recording, and today, we are a full-spectrum provider of workforce management and security solutions having to do with access control and visitor management, with our own hardware, software and in-house services.

Wilhelm (“Willi”) Haller was a thought leader and pioneer in flextime and founder of Interflex
“Overtime is expensive. Flextime can eliminate it.” – Willi Haller (1974)

Wilhelm (“Willi”) Haller was a thought leader and pioneer in flextime, as the concept was first called in the 1960s. A businessman from Germany’s region of Swabia, he went on to become the founder of Interflex. Haller developed the first electromechanical time recording devices, which were based on industrial counters. The goal was to make it possible to record the hours actually worked by employees, making their work schedules more flexible. Experts told him it couldn’t be done. But he proved them wrong!

His view was that flexible working hours would make employees responsible partners in scheduling, so they would be happy with their work. Another objective was to adjust people’s working hours to match actual workloads. Flexible working hours, logged systematically, improved cost-effectiveness at the company due to optimized scheduling of full-time and part-time workers. Rigid working hours, by contrast, brought overloading, absences, and costly work backlogs.

Haller firmly believed flextime would be an important tool for securing employees’ loyalty in times when skilled workers were in short supply. That was a well-known argument then as now.

Milestones in the 50-year history of Interflex

From pioneers to innovators:
The inspiring history of Interflex

Take a journey through the fascinating world of Interflex, a company that has made history and more – it has also been instrumental in shaping the present and future of time recording and access control. From pioneering beginnings to worldwide success, Interflex has come a long way – through it all, always creating solutions that put people first.

Interflex’s early days in Durchhausen, for example in the schoolhouse

On July 9, 1974, Willi Haller founded a new company, Interflex Gleitzeit GmbH, with a small team in Durchhausen, in the Tuttlingen district of Germany’s region of Swabia, becoming the company’s managing director in the process. The company’s purpose was to produce time recording devices. Haller’s goal was to put his own views and ideas into practice in the flextime sector.

But why a butterfly? To those involved at the time, the butterfly symbolized the lightness and freedom to move around and work when people wanted – that is, the main idea behind flextime.

Making working hours measurable – the first product

Interflex 008 was the name of the newly created company’s first product: an electromechanical timer used for time recording. It had a daily program that could accommodate a maximum of eight employees. Small businesses were the main target group. Compared to conventional time clocks, the new solution had the advantage that it was no longer necessary to calculate time worked.

Shifting from mechanical to electronic

In the early years, the company’s products were mainly sold through partners in Germany. At the same time, Interflex launched its first attempt at internationalization, branching out to development and sales contacts in the United States.

One outcome of these transatlantic relations was the development of the 256 / 512 central unit system, the first electronic time recording system with 512 bytes of memory and up to 16 connected recording terminals.

“I decide when I work.”

Willi Haller had his own management style in the role of managing director, as elsewhere. He wanted his employees to share in the company’s success. His system was called “annual working hours,” and it invited employees to decide their own (!) annual working hours depending on their life situation. He also focused on communication and gave employees a voice at the company. Not only did they set their own pay as a group, they also worked longer hours or took time off to compensate for previous overtime work – all while receiving the same monthly pay.

Work should be enjoyable. That’s the only way to get people to do good work.” – Willi Haller (1977)

Hartmut Hennige, originally from the town of Trossingen, joined Willi Haller as one of the original founders of Interflex Gleitzeit GmbH. Driven by technological feasibility, he founded his own company in Durchhausen on September 13, 1975, calling it Interlock Sicherheitssysteme GmbH. The new firm’s purpose was to develop access control systems – unlike Interflex, which focused on the flextime sector. Although the two companies initially took different paths as far as their product ranges and target customers were concerned, they remained in close contact for development and production, including in the years that followed.

Interlock managed to bring an investor with a sound financial backing on board early on: Peter Reisser, a businessman from Stuttgart.

He joined the company in the role of managing director in 1979, when Interlock Sicherheitssysteme GmbH was founded. Based in Stuttgart, Interlock was founded on July 19. Alongside Peter Reisser, Gerhard Kratochwil from Balingen and Hartmut Hennige remained managing directors.

IL 1000: the first electronic access system

Interlock’s first product was the IL 1000 electronic access system. Access control got its start as a secondary product and offshoot of electromechanical time recording. A relay switch in the time recorders made it possible to initiate a door opening quickly and easily when someone clocked in. The Interlock IL 1000 was based on transistor logic and did not yet have a microprocessor. One access authorization for one employee could be stored per memory location. But that meant all memory locations still had to be “programmed” manually on the device. As many as 1,000 access rights could be assigned and up to two doors secured with a single device.

The year of consolidation

Since starting a whole new production facility in the United States seemed unprofitable, a local production site was begun in West Germany. Interflex moved from Durchhausen to the Weigheim district of Villingen-Schwenningen. Production operations moved into a factory building offering 1,500 square meters of space there. Employees joked that the new site looked like a steel mill. It remained the German production location until the early 1990s.

Patented to guard against counterfeiting: CR 32 – the infrared reader

The development of the CR 32 infrared reader was instrumental in the growing success of both Interflex and Interlock.

In the 1970s, magnetic card readers were still very common for applications such as time recording. However, these magnetically coded badges were easy to scan, allowing bad actors to duplicate or copy their codes. The CR 32 infrared reader developed by Interflex for employee identification offered an alternative. This innovative reading method eliminated the risk of duplication. This made it possible to issue employee badges as secure, unique identifiers and use them for time recording and access control alike. The infrared reader was viewed as counterfeit-proof, making it an important catalyst for the two companies’ success in major customer projects. The CR 32 – and its technological successor, the CR 48 – were long installed as card readers in all Interflex and Interlock products. Especially in the access control segment, this method was suitable for companies in the critical infrastructure segment.

Stuttgart-based entrepreneur and Interlock investor Peter Reisser recognized the technology’s potential. This was why he purchased the rights to the Interflex reading and manufacturing process in 1978, paving the way for testing and certification, and then a patent. Certification brought significant benefits for Interlock Sicherheitssysteme GmbH in particular. It allowed the company to win the contract for the access control system in what was then the newly built state criminal police office in Stuttgart, the state capital. The building was constructed to the very highest standards of security that applied in the late 1970s.

Microprocessors: a technological sea change

The first microprocessors marked the advent of a new technology, increasingly replacing electronics in mechanically controlled systems. In cooperation with a development company and IT students from Karlsruhe University of Applied Sciences, Interflex developed a new system based on the latest technology. The fully electronic System 2112 microcomputer system, based on an 8-bit Motorola processor, was born.

The new system was a replacement for traditional mechanical time clocks. It also gave Interflex a technological edge over competitors that were still using mechanical versions. It was more powerful as a central control unit, and it was equipped with the secure CR 32 infrared reader. As many as 1,000 employees could  be integrated into time recording in this way, with a maximum of 16 peripheral devices connected to a system.

System 2112 was smarter than its predecessor, too. The personnel master record was variable. Depending on the configuration, it contained the personnel code number, personnel number, employee name, working hours account (in the sum and difference method), one or more overtime accounts, and a wealth of status and group assignment options. The system was used by industry, government agencies, banks, insurers, and municipal administrations.

System 2112 and its later version, 2212, featured a modular design that Interflex could adjust variably to customer needs. Access control was also possible using the appropriate interface.

The last central control unit

1982 saw the market launch of the multitasking-capable System 5020 for time recording and access control. It featured the last central control unit with additionally installed Interflex hardware. The equipment typical at the time included a computer, keyboard, screen, and printer. System 5020’s modular structure allowed for variable adjustment to customer wishes. It also marked the successful culmination of joint development by Interflex and Interlock.

For example, Interlock developed a memory management unit (MMU) that made it possible to increase the system’s memory from 64 KB to as much as 1,024 KB. With a maximum of eight operating stations, 32 terminals, 20 overtime accounts, 20 absence accounts, 64 daily and 64 weekly schedules, the 5020 was a convenient personnel system.

Processing capacity was up to 1,800 employees. The system was used by industry, government agencies, banks, insurers, and municipal administrations. It was produced in Weigheim. One advantage over competitors in the sense of protecting customers’ prior investments was that the existing data protocol and wiring for terminals that were already installed could be retained.

More flexibility for customers

By the mid-1980s, the shift to electronic terminals controlled on the basis of microprocessors had reached the access control product portfolio as well. The TS 172 and TS 173 (with PIN code entry) were introduced – featuring infrared readers for companies’ stringent security requirements.

This terminal series was highly versatile, as it featured interfaces to connect with all central Interflex control units. For a long time, it was the standard peripheral hardware for the 2112, 2212, 5020 and 5060 systems.

The IT 19X / 29X terminal series for time recording and access control was developed to be the default for the 5020 and 5060 control systems. These were the first terminals with offline functions and their own intelligence and decision-making logic.

All this was in response to changing customer requirements. Companies in the energy supply segment, power plants, and major insurers in particular wanted to be able to process postings offline.

For complex customer requirements

While System 5020, produced in Weigheim, was geared mainly toward the requirements of medium-sized businesses, the early 1980s saw the creation of an alternative solution in Karlsruhe: the 5060 mainframe system, based on a PDP-10 computer from Digital Equipment Corporation (DEC).

Interflex’s aim was to serve the stringent security requirements of complex customers in particular, such as the EUROCONTROL air traffic center in Karlsruhe and the former national nuclear research center Kernforschungszentrum Karlsruhe (since 1995 the Karlsruhe Institute of Technology, or KIT). The project was an important milestone. The experience the company had gained went toward development of new solutions for large, complex customer projects.

Decentralized at the customer’s end: new software system

With the onward march of PCs, including at customers’ end, Interflex made the shift from hardware-based central control unit to a software system operated on-premise at the customer’s location. The move increasingly made Interflex a provider that could offer not only its hardware portfolio, but also software developed in-house.

The IF-5000 system for time recording and access control, developed in the late 1980s, was the first PC-based software system (DOS) from Interflex to control connected terminals.

What had already been hinted at in the form of joint production became a full-blown reality by the mid-1980s. Although Interflex and Interlock served different customer segments with their product ranges, they had never fully lost contact. Joint developments such as System 5020 brought the two companies closer together in production and development, and increasingly in organizational terms as well.

A natural conclusion

On August 28, 1986, Interflex Datensysteme Stuttgart merged with Interlock Sicherheitssysteme GmbH. Interlock Sicherheitssysteme had already been restructured as a holding company in the early 1980s under the new management led by Peter Reisser. This made it easy for this entity to absorb Interflex in 1986.

However, the new company kept a well-known name: Interflex Datensysteme GmbH. Its purpose was development, manufacture, and sale of data collection and related systems. Gerhard Kratochwil and Peter Reisser were named to serve as managing directors. The product portfolio encompassed solutions for time management and access control.

Then, on September 25 of the same year, Interflex grew again, acquiring ISG Interlock Sicherheitssysteme GmbH Ingenieurbüro Stuttgart, a company founded in 1979 by computer scientists Adam Zisler and Harald Weinheimer. ISG’s locations included the company headquarters on Zettachring in Stuttgart (the later headquarters of the new Interflex), which had been founded in 1979, and a development site in Karlsruhe that opened in 1980. The company’s purpose was project planning, development, manufacture, and sales of security systems, especially electronic personnel and operational data systems. ISG was essentially a largely autonomous subsidiary of Interlock Sicherheitssysteme GmbH. It originally started with an engineering firm in Karlsruhe, which worked with students from Karlsruhe University of Applied Sciences in the late 1970s to develop the microprocessor-controlled System 2112.

The company’s focus in the last few years of the 1980s was on developing its own sales structure. In a change from the 1970s, when Interflex had ramped up its work with sales partners, the company was now focusing on its own locations and its own local service directly at customer sites. New branches were opened in Switzerland, Austria, and Germany in the early 1990s. The strategy was to acquire former sales partner companies, as was done in locations such as Hildesheim and Frankfurt, or to establish new locations entirely.

New branches were formed in Belgium (1993) and the Netherlands. These entities continued to have sales partner status in the 1990s and did not become locations in their own right until the early 2000s. Following German reunification, new locations were also opened in the east of the country, in Berlin and Dresden/Kesselsdorf (1991).

Interflex flourished through the 1990s. The company continued to grow under Peter Reisser as managing director, passing the DM 100 million profit threshold and building a sound financial position. In the access control segment, Interflex won many major projects for customers such as DHL, Schaeffler and EnBW. The company also enjoyed a growing positive reputation on the market, receiving its first SAP certificates for the 5060 (VMS-based) and 4000 (based on AIX) systems in 1993.

A new home for production: back to the roots

Once the sales structure had been set up, production operations moved in 1992 from the longstanding location in Weigheim to Durchhausen, the current location. The company chose an open plot of land in Durchhausen, where there would also be sufficient space in reserve for potential expansions. As luck would have it, it turned out to be the same property in Durchhausen for which Willi Haller had had a purchase option years before.

High flexibility, broad hardware portfolio

In 1990, Interflex launched a new type of controller, the new terminal control unit TC 1000, and a new terminal series for time recording and access control, ET 490 to ET 494. The terminal controller worked with a 16-bit Motorola processor and was offline-capable. Users were able to connect it directly to a PC or a Unix system.

The special thing about it was that the data protocol for the TC 1000 controller was a new development, but the protocol between the TC 1000 and the host system remained the same. That made this device family backwards-compatible as a whole and also open to new and more convenient data protocols, both key points in terms of protecting prior investments.

With the 600 generation of terminals for access control and time recording, Interflex had the most varied product portfolio in the mid-1990s, with online and offline capabilities and network capability built in. For example, the IF-1623 was the first terminal to have a built-in controller. The modular structure of the terminals brought tremendous versatility in using a wide variety of reading processes at the customer’s end, from magnetic stripe badges to infrared card readers and beyond to biometric facial and fingerprint recognition systems.

The Proxif RFID reading method, which was developed by Interflex, was standard at the start, but then new RFID reading methods increasingly came to the fore: MIFARE and LEGIC.

The right solution for every customer request

As PCs came to be in widespread use, including among customers, it was no longer commonplace to install entire hardware systems on a customer site. System 5000 was the first PC-based software system from Interflex, but it was still based on DOS. In the mid-1990s, Interflex began developing the first Windows-based software system, IF-6020 (Windows, Unix, Linux). It was the precursor to the present-day IF-6040 software.

The expanded Web-based software is extensive, and in its refined form includes numerous modules for time management, access control, personnel scheduling, and operational data collection. Later, in the early 2000s, visitor management was added, along with the possibility of use as an SAP front end.

Fresh impetus in development: Using time data to control operational processes

How time recording data can be linked in business administration terms to operational and production data to generate key indicators for optimizing processes was the main idea as the company branched out into the world of operational data collection.

At the Durchhausen site, the company forged ahead with development, including the IT-294 BDE and BDE 1744 terminals, which could be used to link production and time recording data for business administration analyses. The idea was still to use pure time data from employees to generate and link added value in business administration terms to optimize processes and operational workflows.

Come under my umbrella: Ingersoll Rand acquires Interflex

A new generation takes charge: Peter Reisser had been the head of Interflex for years. With him at the top, Interflex continued to expand through the 1990s, with strong growth, success, and a sound foundation and international customer projects. But that meant change was coming for the company, in which Reisser had been heavily involved. It was time for a new generation to take charge. On August 30, 2000, Thomas Reisser, Peter Reisser’s son, stepped into the role of managing director for a short time. The international Ingersoll Rand Group acquired a 100% stake in Interflex from Peter Reisser in July 2000. Interflex was a good strategic fit for Ingersoll Rand’s security technologies business, expanding its portfolio.

This ushered in a new era for Interflex and its employees, with increasing structural and organizational change taking shape in the years after that. This brought gains in productivity and efficiency as well as profitability. Annual profit grew by as much as 10%.

Next level: Interflex specializes in workforce management

Ingersoll Rand acquired the Astrum HR personnel scheduling division from Astrum GmbH in September 2005. Astrum’s SP-Expert software expanded the Interflex range of workforce management solutions. It meant that Interflex had an appropriate solution for customers who had additional planning requirements in time management. The acquisition brought in the present-day Erlangen location, but that was not all. About 100 employees joined Interflex as well.

The rise of RFID

In the years after that, Interflex updated its product portfolio by adding a new generation of terminals with an improved microcontroller version: the IF-603 and IF-600 for time recording and access control. The terminals featured graphic touch displays and programmable function keys that garnered them an iF Design Award.

For the first time ever, no infrared card or magnetic stripe readers were included, since the secure LEGIC and MIFARE reading processes had now become standard at Interflex. To help customers safeguard their investments, data protocols were compatible across generations here as well.

The business world slowly began moving away from mechanical locks, which had been dominant until then.

The change meant that as far back as the early 2000s, Interflex was starting to add network capability to its portfolio of locking systems that were operated offline, with door fittings first. The NetworkOnCard solutions from Interflex were born. RFID-capable, writable badge media now made it possible to “carry” access rights from the access control terminal to the appropriate door.

Interflex was increasingly a provider with a well-rounded portfolio of integrated security concepts with access control, biometric identification, offline solutions, video surveillance, and new solutions such as visitor management, along with specific solutions for workforce management in the form of time management and personnel scheduling. Teams of seasoned in-house service professionals served customers at various locations. The development and expansion of the IF-6040 software generation is typical of this successful development. This central system came to function as a business platform with outstanding flexibility, a modular design, and individual configuration options. All this made it possible to meet the various requirements of medium-sized customers, and especially larger ones.

Versatile and user-friendly: the IF-80x terminal generation

Under the eVayo brand, Interflex launched a new generation of terminals, IF-80x, for access control. They were joined by the IF-5735 time recording terminal with touch display and an electronic fitting, PegaSys Office. The online-capable terminal generation and the fitting won the international Red Dot Award (product design, 2012) for their functionality and intuitive design.

The eVayo name was intended to indicate the versatility and flexibility of the new product family. The products could be integrated into all system and operating environments in terms of both looks and functionality. Plus, they were already energy-efficient, a gain for sustainability. They used about 50% less energy compared to the previous generation, IF-70x.

The company continued to consider ways to help customers protect their prior investments, so the new access solution was designed to be compatible with existing installations. Combined with a controller, the powerful, user-friendly readers were able to write NetworkOnCard rights for offline terminals. Touchless identification took place via RFID identification media such as a badge, key fob, or transponder.

As of December 1, Interflex became part of the international Allegion group of companies. The new Allegion was a publicly listed company based in Dublin.

The group’s strategic focus was on security solutions. Allegion had been formed beforehand out of the security division of Ingersoll Rand.

As part of the spin-off, business relations between Interflex and Ingersoll Rand were discontinued as well.

Bernhard Sommer stepped into the role of managing director at Interflex – a position that he shared with previous managing director Bart Michiels. At the same time, Sommer stayed on as the managing director of Simons Voss Technologies GmbH, another Allegion affiliate.

The goal of pooling the two companies’ solution expertise together was to benefit customers with specific requirements in the area of access control in particular.

Although their executive management is the same and they maintain close dialogue on matters of development, investment, service, and marketing, the two companies have operated independently since then.

New product line – Opendor

The trend toward connected security solutions and replacing mechanical locking systems continued.

Interflex launched the Opendor product line, a new generation of wireless-capable battery-operated locking components based on Bluetooth® low-energy technology. The portfolio includes a cabinet lock, lock cylinder, door handle, door fitting, and gateway. It makes it possible to integrate doors that had previously been operated and/or secured offline (in some cases mechanically) into a connected security concept and monitor them online in real time.

Greater customer focus in the Netherlands

There has been growth in the workforce management segment as well, as the company expanded its workforce management portfolio by acquiring WorkforceIT B.V. (Netherlands), a longstanding sales and service partner for the Benelux region. The move strengthened Interflex’s range of solutions and sales structure in the Netherlands.

Synergies bring added value

The company’s expertise and capabilities in the workforce management space continued to grow. Interflex acquired plano., a company specializing in solutions. Now, as plano, it has become a solution brand for the workforce management segment. Interflex also expanded its presence in the Belgian market by acquiring the workforce management consulting business from Cegeka.

Healthcare solution range grows

At the start of the year, plano solutions gmbh, an Interflex solution brand, acquired the business activities of PRO CLIENT GmbH. The move expanded plano solutions’s sales and consulting activities in the healthcare sector. The goal is to continue to expand and strengthen plano’s solution expertise.

Willi Haller took ideas and turned them into reality back in 1974, and the same principles still hold true today. The new brand slogan, “Interflex upgrades your work,” adopted in 2022, reflects our DNA – from 1974 right up to the present day. Now and into the future, our goal is to provide combined solutions comprising proprietary hardware and software and in-house service to support our customers in meeting requirements in the areas of workforce management and access control.

Now more than ever, the objective across the working world will be to ease the burden on valuable skilled workers and strengthen their personal responsibility with efficient solutions – while also taking their individual life situations into account, in keeping with the concept of New Work.

This improves employee loyalty and motivation. Key aspects include the trend toward collaboration tools in workforce management and the digitalization of HR processes to include employees in working hours planning and support workforce co-determination.

Physical security will grow more and more important going forward as well. Security should be viewed holistically, as a mix of digital and physical protective measures. Interflex will also continue to support the trend among many customers toward connected, reliable access control and optimum system integration into building and security management systems.

But with skilled workers in increasingly short supply, new security vulnerabilities could arise if companies lack security and IT managers. This is why Interflex continues to invest in expanding its cloud services to offer customers an alternative to on-premises solutions.

The Interflex logo over time

Each logo has a story to tell, and each one is also an expression of the alignment and design trends at the time. The identity of the Interflex logo has also changed over the past 50 years, showing how we have grown and changed. Amid all these changes, one visual element has been a constant throughout – the Interflex butterfly, a valued part of who we are right from the start.

Growing in line with customer requirements

The true measure of our success is how happy our customers are. That has been our credo ever since our company was first founded. We have always focused on doing more than just supplying products. Our goal is to build and maintain valuable partnerships and to grow and learn from every project. We are proud to say that we are more than just a supplier. We’re a trusted partner, and most of our customer relationships have existed for a long time.

What employees say about Interflex

The employees of Interflex are the heart of the company. With tireless commitment and dedication, valuable contributions, and extensive expertise, they do their part each and every day to make sure we can implement projects reliably and celebrate successes. Positive employee feedback shows that Interflex creates the right conditions for a pleasant work environment as a company.

Looking ahead: our vision for the coming 50 years.

Our people will continue to be at the heart of everything we do at Interflex, now and into the future. Now more than ever, the objective across the working world will be to ease the burden on valuable skilled workers and strengthen their personal responsibility with efficient solutions – while also taking their individual life situations into account, in keeping with the concept of New Work. This improves employee loyalty and motivation.

Key aspects include the trend toward collaboration tools in workforce management and the digitalization of HR processes to include employees in working hours planning and support workforce co-determination. These features let employees organize their own working hours from anywhere, using their own smartphone. Interflex offers a native app called teamtime (iOS and Android) to help with this. It focuses on ease of use.

Physical security will grow more and more important going forward as well – and not just due to new cybersecurity regulations like NIS2 and DORA and the German KRITIS Umbrella Act. Security should be viewed holistically, as a mix of digital and physical protective measures.

But with skilled workers in increasingly short supply, security vulnerabilities could also arise if companies lack managers for security and IT. That’s why Interflex is continuing to invest in expanding its cloud services. This helps medium-sized companies in particular, as it means they need fewer staff for on-premise solutions.

A new generation of terminals will also provide added security going forward. Thanks to the new generation, Interflex will be gradually equipping its wired access readers with new security features that have previously been part of the battery-operated lock components in the Opendor product family. In this way, Interflex is supporting many customers’ desire for connected access control and system integration into building and security management systems.

With an eye to the international alignment of Interflex, customers will continue to benefit from further added value and lasting synergies, now and into the future.
