ActiveIdentification cards - Contactless integrated circuit(s) IC cards - Vicinity cards - Part 3: Anticollision and transmission protocol
识别卡 无触点的集成电路卡 邻近式卡 第3部分：防冲突和传输协议
Application Summary AI generated
This standard specifies the anticollision and transmission protocol for vicinity-type contactless integrated circuit cards, enabling multiple cards to be read simultaneously in a radio frequency field without data collision. It is applied in identification systems such as access control, public transportation ticketing, and logistics tracking where cards must be reliably read at close range (typically up to 1 meter) in environments with high card density.
