Abstract
The invention relates to an RFID tag adapted to access a service of interest from an access terminal, said RFID tag (1) comprising an integrated circuit (3) configured to: enable a cryptographic authentication of the RFID tag (1) by said access terminal (7) using a current cryptography key shared by the RFID tag (1) and the access terminal (7), said authentication allowing access to said service of interest, and enable the RFID tag (1) to recover a new current cryptography key updated by an NFC smartphone after said NFC smartphone has authenticated the RFID tag (1), using an initial cryptography key previously shared between the RFID tag (1) and said smartphone.
