What is RFID?

Radio Frequency Identification – RFID – is an established data-carrying technology used throughout industry. Data relating to an item is stored on a tag which is attached to the item. The tag is activated by radio waves emitted from a reader. Once activated, the tag sends data stored in its memory relating to the item back to the reader. This data can then be shared between organisations and trading partners via the EPCglobal Network in a secure manner.

The use of RFID enables businesses to manage their supply chains with unprecedented levels of automation and a vastly improved degree of control. RFID technology is a fundamental element of the EPCglobal Network.

RFID systems have three main components:

• The RFID tag with its own data, functions and physical characteristics
• The RFID reader (static or portable) with its own functions and physical characteristics
• The host with its own hardware, functions and predefined tasks
