【背景技术】 【Background technique】
在射频通信领域中，出现了多种基于射频通信技术的近场支付通信技术方案，其中基于13.56M Hz的NFC 近场支付技术和基于2.4G Hz的RFID-SIM近场支付技术占主导地位，当然还有基于其他频率或协议的近场支付技术，比如基于125K Hz的近场支付技术等。In the field of radio frequency communication, a variety of near field payment communication technology solutions based on radio frequency communication technology have emerged, including NFC based on 13.56 M Hz. Near-field payment technology and 2.4G Hz-based RFID-SIM near-field payment technology dominate, of course, near-field payment technology based on other frequencies or protocols, such as 125K Hz near field payment technology, etc.
由于基于13.56M Hz的NFC出现较早，目前市场上已广泛铺设了用于识别NFC近场支付技术的终端POS机，这种终端POS机仅支持工作于13.56M Hz的NFC近场支付技术的射频通信卡；如果要使用工作于2.4GHz或其他频率的射频通信卡进行移动识别支付的话，就需铺设对应工作频率的终端POS机；这样就出现多套工作于不同频率的终端POS机并行工作的现象，这对空间利用、铺设成本和/或对现有终端设备的改造来说都是极大的浪费。Due to the 13.56M based Hz NFC appeared earlier, and terminal POS machines for identifying NFC near field payment technology have been widely deployed on the market.
