Barcodes and other kinds of ID tags are everywhere, tracking everything that moves in novel and clever ways. If you turn your head from right to left (eyes open, please), you’ll probably spot at least three items near you that have barcodes on them.
Today, barcodes are used to identify patients in hospitals, validate prescriptions, automate manufacturing processes, log into wifi
networks, exchange contact information, check in airline passengers and movie-goers, check out groceries and other retail purchases, help you track your calories using smartphone apps and much, much more. Recently, I scanned a QR code posted at a bus stop and my smartphone told me how many minutes until the next bus. Oh, and barcodes are also used to track physical assets through the supply chain.
