ISO/IEC 14443
From Wikipedia, the free encyclopedia
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. 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:
- 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
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 (Source from [1]).
This RFID Type is used in the American Express BLUE credit card line.
