Technical Security Unit for tamper-proof
recording of POS data


According to new statutory regulations of the tax authorities, all new electronic and existing PC-based POS systems in Germany must be able to be equipped with a certified technical security device (TSE) from January 1, 2020 and must be updated with a TSE by September 30, 2020 at the latest. Existing POS systems must be retrofitted accordingly by the end of 2022.

The Swissbit TSE is officially certified: the Swissbit-TSE modules (technical security device according to BSI TR-03153), available in three versions, received the release as part of the certification process at the BSI (Federal Office for Information Security) on December 20, 2019. Click to see certification here.

Swissbit solution

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.

Since April 2019 Swissbit TSE has been successfully tested by leading manufactureres in the DFKA field test.

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.

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.

Stand-alone and LAN solution

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 solution with several Swissbit TSEs for the efficient fiscalization of a complete POS system without the need to access any hardware.
