摘要
针对目前超市支付等待排队问题,提出一种基于NFC技术和RFID技术的超市支付系统。系统应用RFID技术提高商品信息的读取速度,应用NFC技术缩短支付时间,应用门禁控制器协调支付流程。硬件部分设计采用模块化方案,提高整个系统的可靠性;并采用3个RFID阅读器并排的结构,以提高电子标签阅读精度。软件部分给出了整个系统软件流程,具体介绍了RFID阅读器阅读流程和NFC支付流程。最后,通过实际应用分析表明,系统具有较好的市场前景。
In order to solve the problem of long period for queuing waiting to pay about the payment system in supermarkets, the new system based on near field communication （ NFC ） and in detail RFID technologies has been proposed. In this system, the reading speed for product information is enhanced by using RFID technology, and the payment time is shortened by adopting NFC technology, in addition, the payment process is coordinated by applying access controller. The hardware is designed with modular scheme to enhance the reliability of the whole system, and the structure with three RFID readers arranged side by side is proposed to enhance the reading accuracy for electronic tags. The flowchart of overall system software is described, and the reading process of RFID reader and NFC payment process are explained. The practical application analysis indicates that the system possesses better marketing prospects.
