RFID Labels & Tags: What are RFID Tags?

RFID Tags are small objects that contain a chip and an antenna for wireless identification of the objects they are attached to (or embedded in) with the help of an RFID reader. Unlike barcode technology, RFID tags do not require line of sight from the tag to the reader and support read/write functionality. Most RFID tags are passive, which means they work maintenance-free, without battery power, for many years.
