Near field communication is a contactless communication protocol between devices like (smartphones, tablets, smartwatches or even credit cards themselves) with a nearby NFC-enabled terminal by simply authorizing your device with a passcode or fingerprint authentication.
Both merchants and customers benefit from near field communication technology, by integrating credit cards, train tickets, and coupons all into one device. Faster payment transaction times and fewer physical cards to carry around.
If your smartphone has an integrated NFC chip, you can use a mobile wallet app like Apple Pay, Android Pay and Samsung Pay for items at retailers that support NFC transactions. Just load up your credit cards on your mobile device and wave or tap your device near an NFC compatible terminal to pay, no card swiping required.
As the technology keeps growing, more NFC compatible smartphones will be available and more businesses will offer NFC card readers for customer’s convenience.
Apple Pay, integrated into the newest generation of Apple mobile devices and incorporates NFC technology. If it becomes widely used by many iPhone users, perhaps merchants will be encouraged to more quickly adopt NFC technology.
Many major banks and credit cards are supporting NFC technology, issuing new cards with embedded NFC chips. This means that you may be able to tap or wave your card at the terminal instead of swiping, no phone required, in the next few years.
