Abstract
A radio frequency identification (RFID) switch tag is disclosed. This RFID switch tag includes a base component having an ultra-high frequency (UHF) booster, and a detachable component having at least one UHF RFID module and a high frequency (HF) RFID module. In some embodiments, the detachable component is positioned in close proximity to the base component in a first configuration of the RFID switch tag such that the at least one UHF RFID module is sufficiently coupled to the UHF booster in the base component to form an UHF RFID system having a desired performance. The detachable component can also be separated from the base component to obtain a second configuration of the RFID switch tag, and the HF RFID module remains functional within the detached detachable component so that the detachable component can be used as a standalone HF RFID tag.

12. A method of using a radio frequency identification (RFID) switch tag, wherein the RFID switch tag includes a base component including an ultra-high frequency (UHF) booster and a detachable component including at least one UHF RFID module, a high frequency (HF) RFID module, and a switching mechanism, the method comprising:
-
positioning the detachable component in close proximity to the base component in a first configuration of the RFID switch tag such that the at least one UHF RFID module in the detachable component is sufficiently inductively coupled to the UHF booster in the base component to form an UHF RFID tag having a desired operating range longer than an operating range of the at least one UHF RFID module; using the UHF RFID tag in a first RFID application that requires the desired operating range; using the switching mechanism to switch from the UHF RFID module to the HF RFID module; and using the HF RFID module in a second RFID application, while the detachable component is in close proximity with the base component. - View Dependent Claims (13, 14, 15, 16)
