摘要
为解决传统读卡器功能单一、不能独立完成金融交易的问题,选择超低功耗而且价格低廉的单片机完成硬件平台的设计;并在芯片内部编程实现金融交易,开发出一套功能丰富、成本低、使用便利的金融IC卡读卡器产品。超低功耗读卡器采用USB接口通信,在读卡器内部实现金融交易能很好地提升金融交易的安全性,同时提高了金融应用开发的工作效率和硬件资源的利用率。
To solve the defection of traditional reader of single function and inability to complete transaction independently, low-power and low-cost MCU is used to design the hardware platform, and program in the chip to complete the financial transactions. The paper develops a feature-rich, low cost, easily used financial IC card reader. The ultra low-power reader uses USB interface to communicate. Carrying out financial transactions in the reader improves security, financial efficiency and hardware source utilization.
