SYSTEM AND METHOD FOR PROCESSING DATA OF RFID TAG MEMORY

摘要

A system and a method for processing data of an RFID(Radio Frequency IDentification) tag memory are provided to reduce repeated data exchange on an RF communication network by temporarily storing data read from the RFID tag memory when the data is exchanged between an RFID tag and an RFID reader. A command converter(20) converts a command received from a user into a tag memory read command. A logical memory manager(21) checks whether a logical cache memory(24) related to a tag(210) is found, and reads authentication data from a tag memory and determines validity of the logical cache memory by the converted command. The command received from the user is performed by using the logical cache memory without reading the data from the tag memory when the logical cache memory is valid. The data is processed through a logical memory(22) by reading the data from the tag memory when contents of the logical cache memory are invalid. A data processor(23) processes the command received from the user by processing tag memory data stored in the logical cache memory or a logical memory.
