RFID Technology
RFID is a general term that is used to describe a system that transmits the identity data 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. Tags - An RFID tag is a tiny radio device, it’s also referred as a transponder. 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 (such as plastic) 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. Different types of RDIF Tags available are passive and active, used as per the RDIF data read / write requirement. 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 application to filter the data and route it to the correct IS application as processed useful information. RFID can help hospitals to locate equipment more quickly, logistics providers to improve the management of moveable assets, brings efficiencies in the supply chain by tracking goods from the point of manufacture through to the retail stores, used as EZ card for toll-collections, remote car door access. Use of RFID technology can increase business productivity and reduce associated costs. Because of such potential benefits of RFID, many of the world’s major retailers have adopted RFID tagging for pallets and cases shipped into their distribution centers.
