Iso/iec 14443

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]


  • Standard 1
    • Parts 1.1
    • Types 1.2

The standard was developed by the Working Group 8 of Subcommittee 17 in ISO/IEC Joint Technical Committee 1.


  • ISO/IEC 14443-1:2008 Part 1: Physical characteristics[1]
  • ISO/IEC 14443-2:2010 Part 2: Radio frequency power and signal interface[2]
  • ISO/IEC 14443-3:2011 Part 3: Initialization and anticollision[3]
  • ISO/IEC 14443-4:2008 Part 4: Transmission protocol[4]


Cards may be 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:

  1. data block chaining
  2. waiting time extension
  3. multi-activation

ISO/IEC 14443 uses following terms for components:

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]
