What is RFID?
RFID is an ADC technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, track objects such as, animals, people, and pets.
RFID is fast, reliable, and does not require physical sight or contact between reader or scanner and the tagged item. RFID is a general term that is used to describe a system that transmits the identity of an object wirelessly, using radio waves. This is referred to as contactless technology and a typical RFID system is made up of three components tags, readers and the host computer system:
Tags - An RFID tag is a tiny radio device that is also referred to as a transponder, smart tag, smart label or radio barcode. The tag comprises of a simple silicon microchip attached to a small flat aerial and mounted on a substrate. The whole device can then be encapsulated in different materials dependent upon its intended usage. The finished tag can be attached to an object, typically an item, box or pallet and read remotely to ascertain its identity, position or state.
Readers -The reader, sometimes called an interrogator or scanner, sends and receives RF data to and from the tag via antennas. A reader may have multiple antennas that are responsible for sending and receiving radio waves.
Host Computer - The data acquired by the readers is then passed to a host computer, which may run specialist RFID software or middleware to filter the data and route it to the correct application, to be processed into useful information.
