RFID (radio frequency identification) is able to track, read and capture information stored on a tag attached to an object (or people and animal) without direct contact needed. The application of RFID technology has been proven impactful in business and everyday life. This highly automatic identification technology transmits data wirelessly, neither contact nor any line-of-sight reading needed. The ability to read multiple items simultaneously substantially saves numerous workloads, man hours, processing time and costs. Each tag-embedded item has unique identity code allows 100% accuracy in tracking its location and information. The greater scope of read range by means of radio signal indicates high flexibility in service installations and wide applications. RFID tags can transmit and receive data. The ability to read, write and rewrite of data provides the updated status of items as they move through the supply chain.
