Abstract
An RFID tag includes a substrate, a chip, a conductive unit, and an antenna. The substrate is attached to an article. The chip is disposed on the substrate to partition the substrate into a first region on one side of the chip and a second region on the other side of the chip. The conductive unit is coupled electrically to the chip, and is disposed on the substrate to form a loop in cooperation with the chip. The antenna is disposed on the substrate and coupled electrically to the chip. The loop and an area of the substrate encompassed thereby are disposed in the first region, and the antenna is disposed in the second region. Removal of the substrate from the article results in a break in the conductive unit, and the chip is operable to detect the break in the conductive unit.
