1. A method of making a multilayer, integral, individual planar radio frequency identification element comprising the steps of:

  • encapsulating at least a first passive radio frequency identification transponder assembly between two plies of flexible porous planar polymer material intimately bonded together around the assembly, each ply being microvoided substantially uniformly throughout, to form a multilayer planar core; and

    scoring the multilayer core to define at least a first multilayer, integral, individual planar radio frequency identification element including the first passive radio frequency identification transponder assembly separable from a remainder of the core.
