TSE - Expiration Date

The certified technical security device (TSE) used in Germany within the framework of the KassenSichV is equipped with special electronic certificates which affect the time of operation of the TSE.

For example, the validity period for swissbit hardware TSEs is as follows:

• produktive TSE: 5 years
• test TSE: 6 months

This means that a productive TSE from swissbit can be used for 5 years at a checkout, whereas test TSEs can only be used for 6 months during the development process. 

The shortened certificate period for development TSEs is a requirement of the Federal Office for Information Security. TSEs that can be used productively do not differ from test/development TSEs, but they cannot be reset to delivery status in the same way as test TSEs.

This is done via the following method:
