Due to combo cards the contactless IC card in communication, and read and write is through the radio frequency to transmit data, so the both sides must abide by the same communication protocol standards to meet the requirements of normal communication. At present, the commonly used non-contact IC card standard protocol for ISO14443A, ISO14443B, ISO15693, etc. Under different protocol standard, corresponding to different IC.
