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.
