Security requirements

Payments card acceptation processes are attended by a range of regulations and standards (EMV, PCI, PIN security etc.). These regulations concern not only POS terminals equipment, their communication and SW, but also processing, transmitting or storing cardholder data and payment transactions data (data security). Main part is attended by acquirers (e. g. banks), producers or HW and SW suppliers, but there is also a considerable part of standards that have to be followed and assured by merchant them self.
