RFID is an automatic identification technology. A basic RFID system comprises of three components: UHF tag, RFID reader and antenna, finally computer. An antenna identifies a tag and this information is collected by a reader. Identification and Information collection is based on radio frequency and does not require physical contact.In another word, a tag is detected by a reader when a tag moves within specific proximity of an antenna. In comparison, a barcode label requires scanning within a specific short distance and line of sight.All data collected, either automatically or manual, is fed to a computer where the application software provides management data and other functions according to needs and requirement.RFID technology is thus used to track and trace objects, providing better business operation visibility and real time information on where any tagged asset is at any given moment. |
Typically, a tag is laminated with a printed label with adhesive backing. The tag is put on an item. When a tag passes within an effective distance of an antenna, the antenna will talk to the tag and obtain its EPC (Electronic Product Code). Many tags can pass by the antenna at once. All the information is relayed to an attached reader by the antenna and the reader will pass the information to a computer, or a server. |
RFID technology is used to track and trace objects, providing better business operation visibility and real time information on where any tagged asset is at any given moment. Therefore, it can be applied to warehouse, to retail as well as many facets of business activities. The auto data capturing feature reduces human errors and provides timely visible operation data for management. |
RFID is being applied in many fields, below are some examples:* Supply Chain Automation/Tracking–Container shipments, trucking movement, vehicle utilization monitor, delivery optimization * Asset Tracking–tracking of documents and assets in offices, labs, warehouses, pallets and containers in the supply chain, books in libraries, document true copies,legal documents * Medical Field–linking a patient with key drugs, personnel giving the drugs, biometric measurements, authentication * People Tracking–security tracking for entrance management or security, contact management at events, baby tags in hospitals to manage access to post-natal wards * Manufacturing/WIP–tracking of parts during manufacture, tracking of assembled items * Retail–Distribution Center operation and shops delivery, tracking store trolleys in supermarkets, active shelves * Warehouse–Real-time inventory by automated registration of items in a warehouse or store-room * Sports/Exhibition–RFID embedded ticket , sports event timing to track athletes as they start a race and pass the finish line |
