| Products RFID Technology Radio Frequency Identification, or RFID, is the new generation Auto ID technology that uses radio or wireless communication to uniquely identify and transmit data relating to an item, object, or an individual Invented in 1948 and first-used during the llnd World War by the US Army for identification of friend or foe (IFF) aircrafts; RF technology gained commercial acceptance during the 1980s and 90s. It is now widely used across a multitude of industry sectors, and applications as varied as an access and security control, livestock identification, airline baggage tracking, automated vehicle identification and toll collection are providing significant improvements and benefits in productivity, efficiency and convenience to organizations and consumers across the globe. RFID Technology: How it works? An RFID system typically consists of three components: Transponder/Tag A transponder, also known as RF Tag, is an enclosed 1C (Integrated Circuit) capable of storing large amounts of data. They are usually attached to an item, asset, or an individual and provide the means for identification. Transceiver/Reader A reader is used primarily to read and write data to RFID tags. A reader can be either hand-held or work as a portable computer or mounted as a fixed device for access control purposes. Antenna An antenna is used to radiate and receive energy in the radio frequency spectrum, from the tag. It could be either stand-alone or packaged together with a reader. In an RFID system, the data is carried in suitable transponders, commonly known as RF tags, and is retrieved at the appropriate time and place by means of an antenna and a transceiver/reader, in order to satisfy a particular application need. A radio signal emitted by the antenna activates the tag allowing it to be read and in some instances data written onto it (active tags). The tag passing through the electromagnetic field detects this activation signal and the reader decodes the tag's encoded data and passes it on to the host computer for information management or system processing. Passive vs. Active Tags Passive tags are read only and gains its power from that generated by a reader and has no internal power source. The reading range is typically shorter (3m or less) and the data storage capacity is comparatively less as compared to active tags (e.g.: 128 bytes). Active tags have both read/write capability and are powered by means of battery, either internal or external. This battery-supplied power enables data to be read and written on to a tag and thus gives it a greater reading range (100m or more) and large data storage capacity (128 KB). RFID: Applications RFID systems allows for non-contact reading or writing of data and are highly effective in manufacturing and other hostile environments where barcode labels cannot survive. Common applications that are widely in use today
RFID: Benefits RFID provides considerable benefits above conventional Auto ID technologies like barcode, and helps to provide a more robust solution to critical business needs. RFID creates a truly automatic way, without any human interface, to collect information about a product, place, time or transaction quickly, easily and without human error.
