Swissbit solution for the German fiscal market

Swissbit will offer a TSE solution for the tamper-proof recording of POS data and has developed a plug-in TSE solution that is extremely easy to integrate. The Swissbit TSE is connected via USB, SD, or microSD interface.

This way the Swissbit TSE can be integrated by both traditional POS systems and POS software manufacturers for PCs or tablets - and is also a very cost-effective solution to retrofit existing POS systems.


According to new statutory regulations of the tax authorities, all new electronic and existing PC-based POS systems in Germany must be equipped with a certified technical security device (TSE) from January 1, 2020. Existing POS systems must be retrofitted accordingly by the end of 2022.

Swissbit is already in the certification process at the Federal Office for Information Security (BSI) with three variants of the TSE and, in close cooperation with the authorities, is ready to deliver a certified TSE in accordance with TR-03153 in time to provide a legally compliant solution for the fiscal market in Germany.

Swissbit TSE

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.

With the Swissbit TSE, cash register manufacturers now have a solution available that can be plugged into any POS system via the USB, SD or microSD interface, making it very easy to integrate and retrofit.

Standalone- and LAN-solution

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 TSE is connected via the USB, SD or microSD interface.
In addition, the future-proof Swissbit solution is cost-effective and easily scalable, as it can be used both as a stand-alone solution and as a LAN solution with several parallel TSEs for connecting different devices such as PCs and tablets without any installation work at the POS system.

As a variant for networked POS systems, the Swissbit TSE can also be integrated into the individual cash register as a LAN-TSE with several Swissbit TSEs for the efficient fiscalization of a complete POS system without any hardware intervention. Enlarge image
