Claim 0:
1. A flat sheet material for radio frequency identification (RFID), 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, the substrate layer comprising an antenna, a chip being mounted on the antenna,
a second intermediate layer on top of the substrate layer, the second intermediate layer encapsulating the chip, and
a second layer of flexible material on top of the second intermediate layer,
wherein the first intermediate layer is made of a polymer composite, and wherein the second intermediate layer is formed by applying the polymer composite in a liquid form between the substrate layer 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.
