ISO/IEC 14443 defines a proximity card used for identification that usually uses the standard credit card form factor defined by ISO/IEC 7810 ID-1. Other form factors also are possible.

Standard

The standard was developed by the Working Group 8 of Subcommittee 17 in ISO's/IEC's Joint Technical Committee 1. The Radio Frequency Identification (RFID) reader uses an embedded microcontroller (including its own microprocessor and several types of memory) and a magnetic loop antenna that operates at 13.56 MHz (RFID frequency). More recent ICAO standards for machine-readable travel documents specify a cryptographically signed file format and authentication protocol for storing biometric features (photos of the face, fingerprints, and/or iris).

ISO/IEC 14443 consists of four parts and describes two types of cards: type A and type B. 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:

PCD

proximity coupling device (or reader)

PICC

proximity integrated circuit card

Implementations

The Calypso (RFID) standard complies with ISO/IEC 14443 part 1, 2, 3 and 4 type B.

MIFARE cards comply with ISO/IEC 14443 part 1, 2 and 3 type A.

LEGIC cards comply with ISO/IEC 14443 part 1, 2 and 3 type A.

Biometric passports comply with ISO/IEC 14443.

All RFID credit cards that have been publicly evaluated use ISO/IEC 14443 type B. This RFID Type is used in the American Express BLUE credit card line.
