Abstract

A method is provided for reading data from an identity document having an NFC chip that supports a READ BINARY command as defined in ISO/IEC 7816. A terminal determines a type of the identity document and, based on that type, identifies whether the NFC chip supports extended-length READ BINARY commands and, if so, determines a preferred extended length for the Le field. The terminal performs access control to obtain access to the NFC chip and reads data from a data group by transmitting a READ BINARY command APDU having an Le value greater than 256 bytes. When extended length is not supported or errors occur, alternate reading may be performed. A terminal configured to execute the method is also disclosed.

Dependent claims

A method for a terminal, for reading data from an identity document, 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 comprising determining a type of the identity document, and based on the determined type of the identity document, determining whether the NFC chip of the identity document supports extended length for the READ BINARY command and if so, determining, 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 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 of reading data from a data group of the NFC-chip, by sending a READ BINARY command APDU to the NFC chip and subsequently receiving 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.
