This part of ISO/IEC 7816 smart card standard specifies:
the contents of messages, commands, and responses transmitted by the interface device to the card and conversely,
the structure and content of the historical bytes sent by the card during the answer to reset,
the structure of files and data, as seen at the interface when processing interindustry commands for interchange,
access methods to files and data in the card,
methods for secure messaging,
access methods to the algorithms processed by the card. It does not describe these algorithms.
It does not cover the internal implentation within the card and/or the outside world.
It allows further standardization of additional interindustry commands and security architectures. For the latest version of this part, please contact ISO in Switzerland.
