RFID is a technology similar in theory to bar codes. However, the RFID tag does not have to be scanned directly, nor does it require line-of-sight to a reader. The RFID tag it must be within the range of an RFID reader, which ranges from 3 to 300 feet, in order to be read.
RFID technology allows several items to be quickly scanned and enables fast identification of a particular product, even when it is surrounded by several other items.
