Patent ID: 7348888

Claim:
An identification device, comprising: an elongated band having a periphery with two elongated sides generally in parallel with each other, the elongated band also having two opposite ends; a non-reusable tamper-resistant fastening arranged to join the two opposite ends to fasten said band around a body part of a user; a transponder circuit attached to said band, the transponder circuit having at least two circuit components that must be electrically connected for the transponder to operate, the transponder circuit being responsive to a received wireless signal, and in response to said received wireless signal, the transponder circuit emitting a wireless signal representative of information pre-stored in the transponder; an electrically conductive, frangible closed loop formed on said band, the electrically conductive, frangible closed loop: providing an electrically closed path between two circuit components of the transponder; and running along substantially the entire periphery of said band such that it is disposed proximate to outer edges of each of said opposite ends and proximate to outer edges of the two elongated sides; said loop being frangible and easily broken in response to an attempt to remove the band from the wearer's body part; and the two circuit components in said transponder electrically connected to said loop and therefore arranged to become disconnected if said loop is broken.
