Claim 19:
20. A flat sheet material comprising a plurality of radio frequency identification (RFID) tags, the flat sheet material comprising:
a first layer of flexible material;
a first intermediate layer on top of the first layer of flexible material;
a substrate layer on top of the first intermediate layer, wherein the substrate layer comprises a plurality of antennae and a plurality of chips, and wherein each chip is mounted on the antenna;
a second intermediate layer on top of the substrate layer, the second intermediate layer encapulating the plurality of chips; and
a second layer of flexible material on top of the second intermediate layer,
wherein the second intermediate layer is formed by applying a polymer composite in a liquid form between the substrate and the second layer of flexible material to cover protruding elements of the substrate layer, and allowing the polymer composite in the liquid state to polymerize.
