Nobody likes queuing at the supermarket waiting for the cashier to scan the barcode on your purchases one by one. Considering that RFID is getting more and more accessible, hopefully we’ll see RFID freely available on every item in the stores, thanks to science. Now researchers from Rice University and Sunchon National University have introduced printed RFID tags made in carbon nanotubes, and the entire process is easy and economical as barcodes. When the RFID transmitter can be embedded into the packaging of the product, we can happily kiss barcodes (and hopefully queues) goodbye at supermarkets. There are still a couple of hurdles preventing this from becoming commercialized, but hopefully the researchers are able to use their smarts to overcome said hurdles.
