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. The development of ISO/IEC 14443 began in the early 1990s, driven by the growing need for secure and efficient short-range wireless communication technologies for identification and payment systems. ISO/IEC 14443 is called contactless short-range standard with a higher RF speed compared to some other RFID standard such as ISO/IEC 15693.
