Unlocking key cabinets using fingerprint authentication

A major municipal energy provider in northern Germany has upgraded its access control system to biometric terminals from our partner TBS. The customer then expressed the desire to retrofit their existing KEMAS key cabinets to also support fingerprint access, in addition to the current method using customer ID cards (standard Legic^® Prime).

These key cabinets store keys for personnel who require access to specific areas, such as external contractors. By integrating biometric terminals into the key cabinets, the risk of unauthorized access due to ID card sharing is eliminated — only authorized individuals can retrieve the keys and access the premises.

Naturally, the customer wanted to keep the conversion effort as low as possible and retain the existing key cabinets. Thanks to close collaboration with TBS and excellent support from our service team in Hamburg, we were able to implement a solution quickly. A newly developed plugin from TBS allowed the existing card readers in the key cabinets to be easily replaced with biometric terminals. No changes were required to the KEMAS application — neither in hardware nor software.

We’re proud to have delivered an innovative solution to the customer in such a short time.
