RFID tag with anti-tamper assembly

A radio frequency identification (RFID) transponder comprising:

• a substrate in communication with a controller and an antenna, the antenna being arranged to receive radio frequency signals, a first side surface of the substrate including a capacitor;
• a device detachably coupled with the substrate via a conductive member positioned between the structure and the capacitor of the substrate, the conductive member being within a desired proximity of the capacitor;
• and
• wherein the structure is attached to an attachment surface so that an attachment strength between the structure and the attachment surface is greater than a force required to decouple the structure from the substrate,
• wherein, when the structure is decoupled from the substrate, the conductive member separates from the capacitor, disabling the transponder.

A method of radio frequency identification (RFID) communications, the method comprising:

• providing a transponder comprising:
• a substrate, an antenna, and a structure, wherein a first side surface of the substrate includes a capacitor,
• detachably coupling the device with the substrate via a conductive member positioned between the structure and the capacitor of the substrate, the structure being attached to an attachment surface so that an attachment strength between the structure and the attachment surface is greater than a force required to decouple the structure from the substrate;
• and
• decoupling the structure from the substrate so that the conductive foam member separates from the capacitor, thereby disabling the transponder.
