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.
