A new generation of chipless RFID tags could soon be set to replace standard product barcodes. A research team at Monash University led by Dr Nemai Karmakar, from the Department of Electrical and Computer Systems Engineering, have been developing chipless radio frequency identification (RFID) tags that can be printed directly onto products and packaging – including postal items, drugs and books – potentially making this new technology cheaper, smaller and faster than any other tracking system on the market.
The team have succeeded in producing fully printable tags for products made of metal and containing liquids including water bottles and soft-drinks cans. Until now, this hasn’t been possible because metal and liquids interfere with the technology. The tag can be printed using an inkjet printer and read when they are attached to reflective surfaces such as metal cans and water bottles.
