RFID switch tag

摘要

Various embodiments of RFID switch devices are disclosed herein. Such RFID switch devices advantageously enable manual activation/deactivation of the RF module. The RFID switch device may include a RF module with an integrated circuit adapted to ohmically connect to a substantially coplanar conductive trace pattern, as well as booster antenna for extending the operational range of the RFID device. The operational range of the RFID switch device may be extended when a region of the booster antenna overlaps a region of the conductive trace pattern on the RF module via inductive or capacitive coupling. The RFID switch device may further include a visual indicator displaying a first color if the RFID switch device is in an active state and/or a second color if the RFID switch device is in an inactive state.

主权项

1. An RFID device comprising:
a booster antenna configured to extend the operational range of the RFID device; an RF module comprising an integrated circuit and a set of one or more conductive traces, wherein at least one conductive trace of said set of one or more conductive traces comprising said RF module is adapted to electrically couple to a coupling region of the booster antenna when said set of one or more conductive traces comprising said RF module is located in a first position relative to the coupling region of the booster antenna; and a switching mechanism configured to move the booster antenna to change the position of the booster antenna between the first position and a second position in which the coupling region of the booster antenna is not electrically coupled to said at least one conductive trace of said set of one or more conductive traces comprising said RF module, wherein at least a portion of the booster antenna is adapted to at least partially shield the RF module when the coupling region of the booster antenna is located in the second position relative to said set of one or more conductive traces comprising said RF module.
