Method and terminal for reading data from an identity document with an NFC chip

Abstract

Method for a terminal, for reading data from an identity document (10, 20), wherein the identity document comprises an NFC chip which supports the READ BINARY command as defined in ISO / IEC 7816, the method comprising, by the terminal: i) in arbitrary order: - a step (310) comprising determining (312) a type of the identity document out of a plurality of identity document types which each comprise an NFC chip which supports the READ BINARY command, and based on the determined type of the identity document, determining (314) whether the NFC chip of the identity document supports extended length for the READ BINARY command and if so, determining (314), based on the determined type of the identity document, a preferred extended length for an Le field of the READ BINARY command APDU to be transmitted by the terminal to the NFC chip; - a step (320) of carrying out access control with the NFC chip to obtain access to the NFC chip; ii) after step i), if it is determined that the NFC chip supports extended length for the READ BINARY command: a step (330) of reading data from a data group of the NFC—chip, by sending (332) a READ BINARY command APDU to the NFC chip and subsequently receiving (334) a corresponding response APDU, wherein a value of the Le field of the READ BINARY command APDU is based on the preferred extended length and is greater than 256 bytes and less than 65535 bytes.
