Identification band using shorting wire for enabling/disabling an RFID transponder contained thereon
First Claim
1. An identification apparatus, comprising:
- a band;
an RFID transponder disposed on the band, the RFID transponder having an RFID circuit and an antenna conductively coupled to the RFID circuit;
a first electrically conductive trace coupled to at least a first part the RFID circuit; and
a second electrically conductive trace coupled to a second part of the RFID circuit, such that the RFID circuit becomes disabled when the first electrically conductive trace conductively couples with the second electrically conductive trace.

Abstract
An identification device formed from a band of material and a non-reusable tamper-resistant fastening arranged to join opposite end regions of the band. A radio frequency identification (RFID) transponder is disposed on the band. The transponder includes an RFID circuit, such as may be formed on an integrated circuit (IC) chip, and an antenna. First and second electrically conductive traces are coupled to different portions of the RFID transponder. The first and second traces are arranged such that the RFID transponder is disabled when the first and second electrically conductive traces come in contact with one another. Various arrangements of the conductive traces are described to achieve improved security and functionality over the prior art.
