| With the second-generation ID card comprehensive renewal, China has entered a full use of RF Reader new era. The second-generation ID cards using a number of high technology, with security, anti-forgery features. DATA IMAGE Suzhou Co., Ltd. is located in the Suzhou Industrial Park, and the company attendance using smart card systems. Recent collaborative research with Suzhou University developed a RF reader module, the original performance appraisal system expansion on the basis of the functions of the reader, card issuers do not have to re-use the circumstances to achieve their ID card directly attendance. This application projects can be made available to all current performance appraisal system and the upgrading of Security, the market has broad prospects.The RF Reader module consists of the MCU and RF base stations chip, the software include a RF base station chip communications segment and with external MCU communications segment. Through SPI interface MCU control RF base stations chip read the second generation card ID or Mifare 1 card ID, then card ID passed to external MCU from the SPI interface.The RF reader module based on the modular design concept, the RF base station chip and MCU integrated in a PCB of DIP package size, through the SPI interface with external connections, hardware middleware as a liaison with the RF card reader. Application developers can get second-generation identification card ID.Finally, the application of the two modules: Attendance band network interface card reader and the campus management system, briefly introduced the design method and its use. Throughout the design process using software engineering methods to test and certify hardware and software carefully and ensure system reliability.
