ISO/IEC 14443
From Wikipedia, the free encyclopedia
ISO/IEC 14443 defines a proximity card used for identification, and the transmission protocols for communicating with it. [1] [2] [3] [4]

[edit] Standard
The standard was developed by the Working Group 8 of Subcommittee 17 in ISO's/IEC's Joint Technical Committee 1.
ISO/IEC 14443 consists of four parts [1] [2] [3] [4] and describes two types of cards: Type A and Type B, both of which communicate via radio at 13.56 MHz. 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:
- data block chaining
- waiting time extension
- multi-activation
ISO/IEC 14443 uses following terms for components:
- PCD
- proximity coupling device (or reader)
- PICC
- proximity integrated circuit card
[edit] Physical size
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]
