RFID transponders today are typically made of thin polymer substrates such as PVC or PET films, a metal antenna and a microchip. In addition, adhesive materials are used to join the different layers together. These materials are similar to those used in standard consumer product packaging.

As demand for RFID transponders grows, especially in consumer applications, SMARTRAC is taking early action to ensure that the footprint these devices leave on the environment is as small as possible. SMARTRAC expect the outcome of the research project will be the discovery of a range of new transponder materials to be used as a base for a “Green RFID Transponder” line.
