ISO/IEC 14443 Identification cards -- Contactless integrated circuit cards -- Proximity cards is an international standard that defines proximity cards used for identification, and the transmission protocols for communicating with it. [1] [2] [3] [4]
The standard is developed by ISO/IEC JTC 1 (Joint Technical Committee 1) / SC 17 (Subcommittee 17) / WG 8 (Working Group 8).
Cards may be Type A and Type B, both of which communicate via radio at 13.56 MHz ( RFID HF). The main differences between these types concern modulation methods, coding schemes (Part 2) and protocol initialization procedures (Part 3). Both Type A and Type B cards use the same transmission protocol (described in Part 4). The transmission protocol specifies data block exchange and related mechanisms:
ISO/IEC 14443 uses following terms for components:
Part 1 of the standard specifies that the card shall be compliant with ISO/IEC 7810 or ISO/IEC 15457-1, or "an object of any other dimension". [1]
