Abstract
In this paper, a designing method of RFID (Radio Frequency Identification) card reading instrument is introduced in detail, and the hardware structure and principle are expounded. By using HY-502 which is a RFID module and LPC2368 which is an ARM core controller, the RFID card information is received and translated to computer by RS232 or USB interface. With the corresponding computer application and database, the card information could be achieved and displayed. The instrument has good prospects in schools, transport, supermarkets, logistics and other fields.
