Introduction
1. Standard Background and Technology Evolution
The contactless reader based on 13.56MHz and 2.45GHz dual-frequency technology is an important part of the mobile payment series standards, aiming to achieve efficient data interaction between smart cards and terminal devices. The standard was proposed by the Ministry of Industry and Information Technology of the People's Republic of China, and the main drafting units include China Academy of Information and Communications Technology, National Technology Co., Ltd., etc.
2. Comparison of standard frameworks
| Standard dimensions | 13.56MHz technical requirements | 2.45GHz technical requirements |
|---|---|---|
| Communication protocol | Comply with YD/T 2497 regulations | Comply with GB/T 33736 regulations |
| Field strength requirements | The magnetic field strength in the transaction sensing space complies with YD/T 2497 regulations | The peak value of the magnetic field strength complies with GB/T33736 regulations |
| Reading and writing distance | 0~4cm can read the card correctly, ≥10cm can not read the card | 0~4cm can read the card correctly, ≥10cm can not read the card |
3. Implementation suggestions
Actual application case:Deploy dual-frequency readers in shopping mall POS terminal equipment to support simultaneous reading of 13.56MHz and 2.45GHz smart cards. The interface control with the POS host is realized through the main control circuit module, and the dual-frequency adapter is used to complete the protocol conversion.
Implementation steps:
- Hardware deployment: Ensure that the reader meets the hardware requirements in Appendix A, including the main control circuit module, 13.56MHz RF circuit module and 2.45GHz RF circuit module.
- Software configuration: Configure the conflict handling mechanism according to application requirements (turn on or off transaction conflict detection between smart cards with different frequencies).
- Test verification: Perform anti-interference tests according to standard requirements to ensure normal operation in Bluetooth and WiFi signal environments.
