ISO/IEC 14443 is an international standard (defined by International Organization of Standardization) for Identification cards / Contactless integrated circuit cards / RFID card, which describes the parameters for identification cards or objects for international interchange.
There are two types under ISO/IEC 14443 standard, that Type A and Type B, both of which communicate via radio at 13.56 MHz (RFID HIGH FREQUENCY). The main differences between these two kinds concern modulation methods, coding schemes (Part 2) and protocol initialization procedures (Part 3). Both Types RFID cards obey the same transmission protocol (described in Part 4).
