The present invention relates to a product ID processing method based on RF ID reset, and in particular, in order to protect personal privacy, a product ID read from a tag attached to a product is modified and stored so as not to leak out based on a network and stored therein. The present invention relates to a method for processing RFID reset based product information to enable recognition and management of corresponding product information.

In the field of ID recognition, bar code systems and magnetic card systems have been used closely with our lives as commodities, credit cards or pay phone cards, but smart cards and RFID cards have been improved through changes in production methods, cultural and technological advances, etc. Is gradually being activated. Among them, RFID is an integrated product using electromagnetic or electrostatic coupling within the radio frequency of the electromagnetic spectral portion to identify an object, an animal or a person. RFID is increasingly being used in the industry as a technology to replace barcodes. The advantage of RFID is that it does not require direct contact or scanning in the visible band for the transfer of information.

Typically, an RFID system consists of an antenna, a transceiver (mostly included in a reader-reader), and a tag (TAG) called a transponder. The transceiver uses radio frequency propagation to carry a signal to activate the transponder-TAG. When activated, the RFID TAG transmits data through the antenna to the transceiver.

Low-frequency RFID systems are used in short transmission areas of less than about 1.8 meters, while high-frequency RFID systems provide long distance transmission capabilities of more than 27 meters.

Such an RFID system consists of a contactless reader and an RFID TAG. The contactless reader continually emits radio waves of constant frequency, and the RFID TAG is wirelessly powered and activated when it approaches the reader's frequency operating range. The RFID TAG activated by the supplied power waits for a command from the reader and sends a response back to the reader when a correct command is received. If the reader sends a command and there is no response from the RFID TAG after the delay defined by the standard, no further communication is made.

Various applications using such RFID TAG and sensor network have been proposed.
