HF-RFID vs. NFC - Can an NFC-enabled mobile phone read ...

up vote 9 down vote

NFC does not only share the same frequency band (13.56 MHz) but it is based on HF-RFID standards.

Specifically, the NFC interface protocol standard (ISO/IEC 18092 / NFCIP-1) uses components from the RFID standards ISO/IEC 14443 (Type A) and JIS X 6319-4. This essentially merges the technologies MIFARE (by NXP) and FeliCa (by Sony). In addition ISO/IEC 21481 (NFCIP-2) defines...

up vote 11 down vote

The ISO 14443 standard defines the physical RF transport protocol for communication between the card and the reader (see e.g. http://www.openpcd.org/ISO14443 for a quick overview). It standardizes things like the use of parity bits, CRC algorithms, frame size, acknowledgement mechanism, etc. There are essentially 2 different types of communication defined: Type A and Type B....
