RFID (Radio Frequency ID)

A wireless non-contact identification system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. The tag contains electronically stored information which can be read from up to several meters (yards) away. Unlike a bar code, the tag does not need to be within line of sight of the reader and may be embedded in the tracked object. RFID technology has significant value for inventory systems, and can also reduce labor costs, simplify business processes, and increase accuracy of inventory counts.
