Scope
GB/T 33742-2017 is the English-translated version of 基于13.56MHz和2.45GHz双频技术的非接触式读写器射频接口技术要求.
GB/T 33742-2017 fixes the requirements for the radio frequency interface of a contactless reader that works on both 13.56 MHz and 2.45 GHz.
It gives the basic characteristics of the interface - communication protocol, field strength, read and write distance, card success rate and interference immunity - and the interface operating mode, covering the basic functions, the connection, the workflow and the resolution of conflicts between transactions with smart cards of the same frequency and of different frequencies.
Informative annexes describe the hardware requirements of a dual frequency reader and a dual frequency adapter. Clause 3 defines dual-frequency reader and transaction conflict.
The standard applies to contactless readers based on the two frequencies and cites GB/T 33736 and YD/T 2497. Issued on 12 May 2017, it has applied since 1 December 2017.

1 Scope
This standard specifies the 13.56MHz and 2.45GHz dual-band technology, non-contact reader RF interface technology requirements, including Interface basic features, interface operating mode and so on.
This standard applies to non-contact readers based on 13.56MHz and 2.45GHz dual-band technology.
2 Normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this document. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 33736 mobile payment based on 2.45GHzRCC (limited field communication) technology of non-contact RF interface technical requirements
YD/T 2497 mobile payment based on 13.56MHz near field communication technology, non-contact RF interface technology requirements
3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Dual-frequency reader
Based on 13.56MHz and 2.45GHz dual-band technology to achieve non-contact reader, can support 13.56MHz and 2.45GHz two non-contact read and write mode.
3.2 Transaction conflict
Multiple smart cards are located in the same dual-band reader's induction work area, dual-band reader will randomly select any one smart card Access and transactions, making the user can not directly determine the access to the smart card, resulting in this transaction is uncertain.
4 Abbreviations
