What is RFID?

Radio Frequency Identification - RFID - is a technology that allows the identification of tagged items without a line of sight. It includes a tag, a reader and a computer system. A RFID tag containing a tiny microchip and an antenna is placed on an object. Most of the RFID tags, which usually carry information in the form of a unique serial number, require no external power.

A bar code carries data in a visible symbol and is read by a bar code scanner using optical or infrared wavelengths. An RFID tag carries data programmed into a small computer chip and operates at a wide range of radio frequencies.

The tag is activated by radio waves emitted from an RFID reader. The reader communicates wirelessly with the tag across what is known as the air-interface. Once activated, the tag sends data stored in its memory relating to the item back to the reader. This data can then be used within and between organisations and trading partners in a secure manner via the EPCglobal Network.

The use of RFID enables businesses to manage their supply chains with unprecedented levels of automation and a vastly improved degree of control.
