Switzerland, officially the Swiss Confederation, is a federal republic composed of 26 cantons, with federal authorities based in its capital- Bern.
The main state institution engaged in economic and financial topics is the Federal Tax Administration (FTA).
Switzerland is not a fiscal country and has no specific laws or other regulations specifically dedicated to the topic of fiscalization.
None of the laws in Switzerland require the usage of specific equipment, hardware, or software when creating, processing transactions and/or issuing receipts to customers.
There is no online or real-time communication with the TA.
There are also no limitations or restrictions regarding the choice of equipment that would be used by a particular retailer; the choice is made based on business needs and internal organization.
