RFID Centre - RFID

RFID is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. This is sometimes referred to as contact-less technology and a typical RFID system is made up of three components: tags, readers and the host computer system.

RFID in Action

To repeat the key point, using RFID is simply a matter of reading the associated tag to get the unique ID. Once you have the unique ID, it is simple data.

Why use RFID - ThingMagic.com

There are multiple reasons one would want to use RFID:

Use RFID if you want to wirelessly identify something without line of sight. Line of sight means that one could draw a straight line going directly from the reader to the object without interruption. This is literally what is done for bar codes via a laser, but mirrors are used to make the laser look a little fancier. If the laser can't...
