ABSTRACT:
A radio-frequency identification (RFID) tag includes a facestock and a liner. The facestock includes an RFID circuit with an operating parameter, and the liner is releasably attached to the facestock such that when the liner is detached from the facestock, the operating parameter of the RFID circuit is desirably modified. The RFID tag may be configured so that the operating parameter that is modified is, for example, a read range or a propagation direction. The RFID circuit may include an RFID chip and an antenna, and the liner may include an electrical element that modifies a read range of the RFID circuit when the liner is attached to the facestock. More specifically, the electrical element may electrically couple with the antenna when the liner is attached to the facestock, thereby reducing the read range of the circuit. When the liner is removed, the antenna is decoupled from the electrical element and thereby enabled to operate at another read range, i.e., a specified operating range. Alternatively, the electrical element may couple with the antenna of the RFID circuit so that energy is propagated from the element in a direction that is orthogonal to a normal direction of propagation of the antenna.
