Scope

GB/T 33736-2017 is the English-translated version of 手机支付 基于2.45GHz RCC(限域通信)技术的非接触射频接口技术要求.

GB/T 33736-2017 specifies the contactless radio frequency interface used for mobile payment over 2.45 GHz RCC, range controlled communication.

It defines the short-range wireless communication interface and the information exchange protocol: how the protocol is divided into layers, the protocol data units of the magnetic channel and of the RF channel, and the physical, data link, transport and session layers, down to symbol rates, data encoding and modulation, frame structures, packet formats and message codes.

It also gives the basic protocol flow, the anti-collision mechanism and the session commands, with normative annexes on RF parameter calculation and on the cryptographic algorithms.

It is one of a series of standards for mobile payment over 2.45 GHz RCC and over dual-band 13.56 MHz and 2.45 GHz technology. Issued on 12 May 2017, it has applied since 1 December 2017.
