Abstract
A radio frequency identification (RFID) transponder may include a substrate and a device. The substrate may be in communication with a controller and an antenna, and the antenna is arranged to receive radio frequency signals. A first side surface of the substrate may include a capacitor. The device may be detachably coupled with the substrate via a conductive member positioned between the structure and the capacitor of the substrate, and the conductive member may be within a desired proximity of the capacitor. The structure may be attached to an attachment surface so that an attachment strength between the structure and the attachment surface may be greater than a force required to decouple the structure from the substrate. When the structure is decoupled from the substrate, the conductive member separates from the capacitor, disabling the transponder.
