RADIO FREQUENCY IDENTIFICATION READER, RIFD TAG, RFID COMMUNICATION METHOD AND SYSTEM USING SERIAL COMMUNICATION PROTOCOL

摘要

PURPOSE: An RFID(Radio Frequency Identification) reader, RFID tag, RFID communication method, and system thereof are provided to execute wireless communication through a serial communication protocol without using specific wireless communication protocols. CONSTITUTION: An RFID tag(220) includes tag information. The RFID tag provides interfaces by using a serial communication protocol. An RFID reader(210) reads the tag information by using the serial communication protocol from the RFID tag. The RFID tag includes a tag control module. The tag control module provides the RFID reader and the interfaces by using an I2C(Inter-Integrated Circuit) or an UART(Universal Asynchronous Receiver Transmitter).
