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.
