Interflex – Solution
for access and time

We develope, produce and distribute combined hardware and software systems for Security Solutions and Workforce Management since 1974. Our many years of experience guarantee you consistently high quality standards.

This is Interflex

When do you actually go to work? When you have to or when you want to? This question has been on our minds at Interflex for almost 50 years. It’s what drives us to develop solutions and products that allow you to freely and flexibly manage your most important resource – your time.

The focus on people

Wilhelm Haller was also concerned with how to use time wisely when he founded Interflex in Durchhausen in the district of Tuttlingen in 1974 and launched his first time recording system on the market. For the Swabian social entrepreneur and pioneer of flextime, the focus of his work was always on people and the compatibility of work and private life. A concept that is on everyone’s lips today as work-life balance. That is our DNA.

Everything from a single source

Time and attendance has not been the end of the story; over the decades, we have successively expanded our portfolio. It includes holistic solutions for workforce management with time and attendance, time management and workforce scheduling as well as innovative security solutions for access control and access control with visitor management. Interflex is a leading international provider with several thousand system installations, which are used to manage around 4.7 million employees every day. All solutions and products are “Made in Germany” and can be modularly adapted according to your individual requirements – regardless of company size and industry. Interflex is represented throughout Germany at twelve locations and operates subsidiaries in Austria, Belgium, the Netherlands and Switzerland.

Work easier

At Interflex, we want to empower you and your employees with our high-quality solutions and products to master your challenges in working life easily and flexibly. So that you can freely dispose of your time and continue to go to work when you want to – and not when you have to.
