The employees log on to the system with an ID card. The machine provides the key assigned to the employee. The removal must be documented electronically. When returning the key, the employee logs in again, selects Return from a menu, and an accessible compartment is displayed.

The employee puts the key into the locker. Check whether the “correct key” was returned. The return is to be documented.

Certain persons must have access via remote access or similar to see which person has which key and which keys are stored in the system. If necessary, a time control would make sense within the time window of the keys must be returned, or an alarm message is generated (optional). Lock data and access data must also be able to be queried or changed.

The system’s software should function autonomously, independent of the customer’s system. Cloud and web solutions are permitted under the data protection guidelines prescribed in Germany.
