| 20090315716 | Identification band using serpentine paths to detect tampering - A tamper-resistant RFID wristband that becomes permanently disabled upon tampering. The wristband includes a plurality of holes for snugly securing the band to a wearer, an RFID circuit, and an electrically conductive loop disposed in the band. The RFID circuit and the conductive loop are electrically coupled to form a series circuit, severance of which disables the wristband. The electrically conductive loop includes a first layer and a second layer that are electrically isolated from one another, save for at least one electrical connection made preferably by a via at the end of the band distal from the antenna element. The first layer encircles the holes in a serpentine path on one layer of the band and the second layer encircles the holes in a complimentary serpentine path on a different layer of the band | 12-24-2009 |
| 20100012733 | Identification band using a conductive fastening for enhanced security and functionality - 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 in the band. The transponder includes and RFID circuit, such as may be formed on an integrated circuit (IC) chip, and an antenna. In the present invention, the tamper-resistant fastening serves additional functions beyond securing the opposite end regions of the band together. Namely, the fastening can be made of a conductive material and designed to create electrical continuity between multiple conductors to enable or disable certain circuit functionality. In one variation, this continuity allows the excess tail portion of the wristband to be cut without disrupting circuit functionality. In another variation, the fastening mechanism is designed to crimp conductors together. In yet another embodiment, the RFID circuit itself is wholly or partially formed within the fastening mechanism to better protect and support the circuit, as well as to make it more difficult to defeat the tamper-resistant functionality of the device. | 01-21-2010 |
| 20100095522 | Method of manufacture of an identification wristband construction - A method of manufacture of a wristband includes the steps of providing a bottom substrate. First circuit elements are deposited on the bottom substrate. A dielectric material is deposited at predetermined areas on the bottom substrate. A remainder of the circuit is deposited on the bottom substrate and dielectric materials. A transponder chip is secured to the bottom substrate to form a transponder. A second substrate is affixed to the bottom substrate such that the dielectric material and transponder are disposed between the bottom substrate and second substrate. | 04-22-2010 |
