NFC or Near Field Communication to give it its full title, is a way for devices to exchange information with each other without having to plug in or even physically touch each other. Soon it will be used to create “contactless” payments where you can simply place your credit, debit or even phone onto a pad and the retailer can charge you for your purchase in seconds.
How does NFC work?
NFC uses small chips, sometimes called tags that have no power of their own but when scanned by an NFC reader a small electromagnetic charge brings the NFC tag to life and the data contained can be accessed by the reading device. A device can be both a reader and able to write to NFC tags and tags themselves can be write once or written to many times over.
