RFID tag - Computer Definition
An electronic identification device that is made up of a chip and antenna. For reusable applications, it is typically embedded in a plastic housing, and for tracking shipments, it is usually part of a "smart" packaging label.
Reusable Hard TagsFor RFID applications such as toll collection and vehicle and container tracking, the tags are used over and over for many years. Such tags are built into a plastic housing like handheld calculators and other electronic devices.
Smart LabelsA smart label contains the RFID tag as well as printed bar codes and alphanumeric characters. The printed material can provide redundant UPC and EPC data that can be picked up by a bar code scanner or read by a warehouse employee if the RFID tag cannot be read. RFID smart labels are printed and encoded at the same time in an RFID printer. The RFID portion of the smart label is called an "inlay" and is adhered to the back of the paper label, very often by a different manufacturer. See RFID inlay and RFID.
