Abstract: Near field communication (NFC) is used for banking, access control or identification. The NFC-chip contains data verifying the identity of the holder, which is read by an NFC-chip reader. NFC-chip readers are now often online or stand-alone terminals, which may be trusted or untrusted. Trusted terminals may require a communication link to a certificate server. Untrusted terminals require a link to a server that performs the authentication steps and may require a link to a certificate server. A disadvantage of conventional NFC-chips and readers is that it can be challenging to position NFC-chip readers at remote or other arbitrary locations. A solution is found in a method for communication with an NFC-chip of a user identification document, by which a terminal obtains protected data from the NFC-chip, including the step of verifying the integrity of the protected data; and a server verifies genuineness of the NFC-chip communicating via the terminal.
