RFID Technology


RFID or Radio Frequency Identification is the technology used to transfer data from an Electronic Tag using radio frequency waves. The Tag called RFID Tag or RFID label is attached to an object and the data is collected in a RFID Reader to track the object. The signals from the Tag can be collected by the reader even if the Tag is located far away from the line-o-sight of the tag. The RFID tracking is a form of automatic identification technology using a unique serial number in the tag.
