Think about it, shopping has never been easier or quicker, with the swipe of a barcode. Not to mention, we can get into buildings using voice recognition and fingerprints, instead of fumbling around for the key. In an age of information overload, we store hundreds of work and other documents on the cloud and can access them very conveniently on any connected device, any time, anywhere.
So how does it work?
Radio frequency identification or RFID is used widely to automatically identify and track tags attached to objects. The tags contain electronically stored information about the objects, such as product identification, point of purchase/use, track and trace and distribution (think of factories, distribution warehouses, or anything you buy and pay for by simply swiping the barcode).
International Standards produced by the IEC joint technical committee with ISO, ISO/IEC JTC 1/Subcommittee (SC) 31 cover automatic identification and data capture (AIDC) techniques, including for bar code symbologies and RFID.
