What is NFC?
Near Field Communication is a wireless data transfer technology that transmits information over short distances between an NFC chip and a NFC enabled smartphone.
NFC tags can be programmed to contain an endless array of functions from directing you to websites to paying for parking.
NFC vs. QR codes
QR codes: bar codes you scan with a QR code reader app on your phone.
NFC: tags you tap with a NFC-enabled smartphone.
These technologies are similar and the end result is the same. However, there are a wider array of actions that can be performed with NFC.
