Since 1 January 2020, POS systems have to fulfil additional legal requirements, so that all cash registers in Germany now have to be equipped with a so-called technical security device (TSE).
TSE web service and TSE module can be used in ‘combi mode’
Fiscalization - Product details
Bundesdruckerei has implemented the technical security device (TSE) in two solution variants: a TSE in the form of a microSD card (TSE module), which can also be used with an adapter for USB and SD card connections, as well as a web service operated jointly with the Deutsche Fiskal company.
The TSE prevents sales suppression and tax avoidance.
In technical terms, this is possible by attaching an electronic signature to the individual receipts. Cash registers that were bought after 25 November 2010 and which cannot be retrofitted can still be used until 31 December 2022.
In Germany, the technical security device (TSE) must be accredited by the Federal Office for Information Security (BSI).
TSE-Modul
Bundesdruckerei has developed two solutions to implement the legal requirements and to counteract manipulation of POS systems: a TSE module that combines all TSE functions in a compact micro SD card and a web service with central hosting at Bundesdruckerei's trusted service provider, D‑TRUST GmbH, which fulfils the function of a TSE.
The term fiscalization sums up the legally compliant implementation of the extensive requirements of the German tax authorities for tamper-proof POS systems. The secure signature of each transaction is designed to prevent cash register tax evasion. Implementation must be completed by 31 December 2019.
The TSE is a certified technical security device with three components:
Security module: The security module ensures that cash register entries are logged as soon as the recording process begins and cannot be changed later without being noticed.
Storage medium: The individual records are stored on the storage medium for the duration of the retention period required by law.
Uniform digital interface: The digital interface is designed to ensure smooth data transmission for testing purposes.
