Introduction to RFID

The term RFID (Radio Frequency IDentification) describes the use of
radio frequency signals to provide automatic identification of items.
RFID is a flexible technology that combines advantages not available
with other identification technologies. It is convenient, easy to use, and
well suited for automatic operation. RFID does not require contact or
line-of-sight to operate, it can function under a variety of environmental
conditions and provides a high level of data integrity.
Radio waves transfer data between an RFID reader and an item to which
an RFID tag is attached. The tag can contain data about the item, such
as what the item is, what time the device traveled through a certain zone
and so on. RFID tags can be attached to virtually anything—from a
vehicle to a pallet of merchandise.
RFID is similar in concept to bar coding. Bar code systems use a reader
and coded labels that are attached to an item, whereas RFID uses a
reader and special RFID tags that are attached to an item. Bar coding
uses optical signals to transfer information from the label to the reader;
RFID uses radio frequency signals to transfer information from the
RFID tag to the reader. However, an RFID tag can hold significantly
larger amounts of data and can be rewritten many times which are
obvious advantages.
