Abstract
Methods and apparatuses for assembling and implementing tamper indicating RFID devices are presented. An RFID device includes a substrate, an electrically conductive pattern formed on the substrate configured to operate as an antenna by separating a portion of a first device section from a second device section, and an electrical circuit mounted on the substrate that is electrically coupled to the antenna. The electrical circuit stores an identification code.
