Design And Research Of High Frequency Card Reader Based On RFID Technology

RFID (Radio Frequency Identification) technology has attracted more and more attention in recent years. As a data acquisition terminal card reader is a key device since it is the first step in the work of a whole RFID system. In current market, however, most card readers just has single function, and is only suitable for stationary occasion. This paper designs a portable multi-function RF(Radio Frequency) card reader system with13.56MHz working frequency, which can read and write electronic tags supporting the ISO14443protocol and ISO15693protocol, and can be used in many occasions.This paper firstly presents the design scheme of bottom hardware and software of the card reader system respectively from the power module, RF module, control module, display module, key input module, memory module and communication module; and then designs communication protocol structure, software function, GUI(Graphical User Interface) three aspects of the PC software in details, at last tests the whole function of system and reliability of data communication. The test results show that the designed card reader system works well.
