Philips Research demonstrates world's first 13.56 MHz RFID tag based on plastic electronics.

A plastic electronics RFID chip can be printed directly onto a plastic substrate along with an antenna. This could enable the packaging industry to replace existing barcodes by a low-cost RFID tags.
Yesterday we reported about the World's Smallest RFID Tag developed by Hitachi. It seems to me that for retail products the plastic based RFID tags might be better suited.

Performance results for these RFID circuits will be presented at this year’s International Solid-State Circuits Conference (ISSCC, February 5-9, San Francisco, CA, USA) in a paper that will also be awarded the conference’s Beatrice Winner Award for Editorial Excellence.
