METHOD AND SYSTEM OF CONTACTLESS AUTHENTICATION, AND CARRIER OF PIN CODE

摘要

The method and system of authentication over a PIN code within a separate identifier (3) during a cashless payment realized over the payment terminal (1) is based on the fact that a unique identification file containing the data on a current payment is sent from the payment terminal (1) to a distance lower than 10 cm into the identifier (3) put to the payment terminal (1). The identifier (3) is supplied with energy (received and/or received and accumulated energy) in a contactless way over the payment terminal's (1) electromagnetic field. The PIN code is assigned to the received identification file in the identifier's (3) processor, the resulting file is signed electronically using the private key stored in the identifier's memory (6) and the electronically signed file thus created is sent to the payment processing centre (2) for the verification of the PIN code's correctness.
