It is clarified that an active POS means a POS that can be used to complete transactions with a card, even when it is used or available as a backup, in the case of a functional failure or other emergency.
At the same time, on the AADE website, a special page has been created for the POS (Cash Systems Interface), from which businesses and other stakeholders (accountants, providers, etc.) can be informed about:
- the individual obligations of each person involved
- the cash register and POS options available
- the schedule and progress of the project.
