Abstract:
A POS payment terminal (1) using a mobile communication device (4), such as a mobile phone, is created over a temporary connection between the merchant's Sales Device (2) with the removable memory card (18), where the removable memory card (18) is inserted into the customer's slot of the mobile communication device (4). The Sales Device (2) contains a secure memory (6) with the POS terminal's identification data in the form of a SAM card or an ICC card (9) or directly in the form of a secure element on the circuit printed. The payment terminal (1) is created before or during the payment process over a temporary connection between a Sales Device (2) with a mobile communication device (4), which is held by the customer and which has a removable memory card that can have an independent communication element, especially of the NFC type. The payment cryptogram is of standard form, e.g. in the EMV format and it is sent online or offline in batches to the payment processing center (15) according to the amount paid and the preset risk management.
