RFID (wireless electronic tag) reads the tag information attached to the product using the RFID tag 10 including the unique information attached to the product and the wireless communication technology of the 13.56MHz or 900MHz RFID frequency band. is a system for transmitting the RFID reader 20 and information recognized by the RFID reader 20 to the application of the host computer 30 through the RFID middleware.

1 is a configuration diagram of an existing 13.56 MHz RFID tag, an RFID reader, and a system.

RFID technology for product management is standardized in ISO/IEC JTC1 SC31, and ISO/IEC 18000 series defines Air Interface Protocol for each frequency between RFID reader and tag.

RFID frequencies are 135 kHz, 13.56 MHz, 433 MHz, 860-960 MHz. 2.45 GHz band is used. The low-frequency 13.56MHz RFID system is used to recognize tags attached to products, and the recognition distance is only a few centimeters. The high-frequency 900MHz UHF RFID system proposed and used by EPCGlobal can recognize up to 100m. used

Mobile RFID convergence of NFC Forum provides mobile RFID information service using mobile phones of 13.56MHz RFID frequency band and connects with EPCglobal's UHF band 900MHz RFID frequency band in the logistics and distribution field (B2B, B2C) to achieve B2B2C mobile RFID convergence is presenting

2 is a diagram showing the UHF 900 MHz band RFID frequency standards for each major country.

As for the frequency of UHF band RFID use by major countries, 902-928MHz ISM (Industrial, Scientific, and Medical) band is used as the RFID frequency band, and the occupied bandwidth of one channel is 500kHz, using more than 50 channels. 865-868MHz is used as the RFID frequency band, and the occupied bandwidth of one channel is limited to 200kHz, and there are only 15. Australia has 918-926MHz, Korea has 910-914MHz bandwidth similar to Europe, and Japan uses 950-956MHz.

The RFID reader and the RFID tag are composed of a forward link and a reverse link according to a transmission direction of information. The forward link transmits a command signal and a continuous wave (CW) signal that supplies power to the tag to obtain the tag's unique information from the RFID reader to the tag. The reverse link is a process until the tag reaches the tag signal to the RFID reader through the reverse scattering process based on the CW signal received from the RFID reader. The RFID tag consists of a tag chip containing unique product information and an antenna. It is classified into an active tag and a passive tag according to the power supply method.

The active tag uses battery power inside and can collect information independently of the RFID reader. As the battery is built-in, the price increases, and the size and weight increase. When the life of the battery expires, the use period expires and the function as an RFID tag is lost.

A passive tag generates DC power from an RF signal received from an RFID reader to drive a tag chip. Communication between the passive tag and the RFID reader is asynchronous, and when there is a response request from the RFID reader, the passive tag transmits data through backscattering modulation. The passive tag does not have a separate power source and receives the driving power of the RFID tag by the power received from the RFID reader.

A system equipped with an RFID tag and reader is being applied to many fields such as product production management, inventory management, distribution, sales management, logistics, ports, import and export customs clearance, pharmaceutical and pharmaceutical industries, medical devices, and defense ammunition management.
