RFID switch tag

1 . A switchable radio-frequency identification (RFID) tag device comprising:

a case:

a first RFID module positioned on a first plane;

at least one un-tuned antenna section positioned on a second plane, wherein the first plane is positioned parallel to the second plane;

a second RFID module positioned on the first plane;

a third RFID module positioned on the first plane; and

a rotatable switch configured to move between a first position, a second position, and a third position; and

wherein, in the first position, the first RFID module is coupled to the at least one un-tuned antenna section to form a tuned RFID tag, and the second and third RFID modules are detuned and/or inoperable; and

in the second position, the second RFID module is coupled to the at least one un-tuned antenna section to form a tuned RFID tag, and the first RFID module and third RFID module are detuned and/or inoperable; and

in the third position, the third RFID module is coupled to the at least one un-tuned antenna section to form a tuned RFID tag, and the first and second RFID modules are detuned and/or inoperable, wherein:

the rotatable switch causes a first visual indicator to display or be indicated on the case when in the first position, and

the rotatable switch causes a second visual indicator to display or be indicated on the case when in the second position, and

the rotatable switch causes a third visual indicator to display or be indicated on the case when in the third position.

2 . The device of claim 1 , wherein the first, second and third RFID modules include an integrated circuit and a conductive trace pattern.

3 . The device of claim 1 , wherein the first, second and third RFID modules are formed on a first substrate, the first substrate being positioned on the first plane, and the at least one un-tuned antenna section is formed on a second substrate, the second substrate being positioned on the second plane.

4 . The device of claim 1 , wherein the first, second, and third RFID module, the at least one un-tuned antenna section, and the rotatable switch are enclosed in the case.

5 . A switchable radio-frequency identification (RFID) tag device comprising:

a first RFID module, a second RFID module, and a third RFID module, each including an integrated circuit and conductive trace pattern;

a rotatable switch mechanism, wherein rotation to one of a plurality of positions selects which RFID module is operational; and

a plurality of tuned antennas arranged in a common plane, each selectively coupled to a respective RFID module via the rotatable switch mechanism;

wherein a plurality of tuned antennas are selectively coupled to a respective RFID module via the rotatable switch mechanism,

wherein, the first RFID module, the second RFID module, or the third RFID module is electrically coupled to a corresponding tuned antenna to form a tuned RFID tag, and the other RFID modules are electrically isolated or detuned such that they are inoperable, and

wherein the rotatable switch mechanism provides a mechanical or haptic feedback at each position.

6 . The device of claim 5 , wherein each tuned antenna is tuned to a distinct frequency band, enabling frequency-selective operation of each RFID module.

7 . The device of claim 5 , wherein the rotatable switch mechanism comprises a dial or knob.

8 . The device of claim 5 , wherein the rotatable switch mechanism is magnetically actuated.

9 . The device of claim 5 , wherein the RFID modules further comprise shielding elements to prevent interference between RFID modules when only one is active.

10 . The device of claim 5 , wherein at least one antenna element comprises a booster antenna that is inductively coupled to its respective RFID module without a direct electrical connection.
