Can there be any problems with the cash register in the Czech Republic when canceling EET?

Once the EET is abolished, the cash register can no longer establish a connection with the EET system. In practice, there may be situations similar to an internet connection failure, when a receipt containing the PKP code (taxpayer signature code) instead of the FIK code (fiscal identification code) is issued to cash registers. The cash register will repeatedly try to send data about the registered sales via a data message, but the cash register no longer can receive the confirmation message from the EET system due to the system being turned off.

If the cash register has a function that allows you to "turn off" the recording of sales, we recommend turning off this function on the cash register so that it no longer connects to the EET system. However, individual cash registers may react differently to the shutdown of the EET system by the Financial Administration.
