The Swissbit TSE combines the "Cryptographic Service Provider (CSP)" and the application "Security Module Application for Electronic Record-keeping Systems" (SMAERS) with the certificates and the storage medium.

8GB of NAND storage is available for both secure fiscal storage for signing fiscal transactions, and free-user storage. The latter can be used by the system for other tasks.

The digital interface handles the capture of transactions, the secure export of fiscal data and the administration of the TSE.

Cash register manufacturers can easily integrate the Swissbit TSE solution into their POS systems. In addition to the TSE, Swissbit also provides an SDK (Software Development Kit), drivers and support for Windows, Linux, Android and embedded systems. The Swissbit USB TSE is connected via the USB interface.
