Abstract:
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.
