1. A personal identification device comprising:
- a planar radio frequency identification element, the element including a flexible core having opposing first and second major opposing outer sides and formed from at least two layers of flexible polymer sheet material, at least one layer being a flexible, porous polymer sheet material, and a first planar radio frequency transponder assembly operating at a first frequency and a second separate planar radio frequency transponder assembly operating at a second frequency different from the first frequency permanently and integrally fixed between the two layers of the flexible polymer sheet material, each of the first and second transponder assemblies including an antenna and an integrated circuit chip; and
carrier means configured for holding the planar radio frequency identification element and for releasably securing the planar radio frequency identification element to a user to be identified by the planar radio frequency identification element.

Abstract
Each personal identification device includes a planar identification element with at least a core of flexible, porous and preferably microvoided polymer sheet material and a planar RFID assembly encoded with a unique electro/magnetic code permanently and integrally joined together with the core. The sheet material is sufficiently porous to collapse around the core so the sheet product remains planar yet flexible. A separate carrier can be provided or devices can be made in batches with scoring define one or more individual RFID devices removable from a remainder of a sheet product.

19. A method of making a radio frequency personal identification device comprising the steps of:
-
providing an at least generally planar multilayer flexible polymer material sheet intermediate product containing first and second radio frequency identification transponder assemblies operating at different first and second radio frequencies; and scoring the intermediate product to define at least one multilayer, integral, individual planar radio frequency identification wristband removable from the intermediate product, the planar radio frequency identification wristband including a central holder portion containing the first and second radio frequency identification transponder assemblies and strap means extending away from the central holder portion, the strap means being of a length sufficient to be able to be completely wrapped around the wrist of a user to secure the wristband to the user. - View Dependent Claims (20)
