One of the biggest things that will come with near field communication is the way we make payments. Google Wallet is already helping by allowing you to store all of your credit card information in one place. And there are many vendors that already have NFC technology built right into their systems. So rather than pull out a card, swipe, put it back in the wallet, then hurry to sign the slip while people are waiting for you, just touch your phone to the NFC pad. It’s fast, safe, and even if you lose your phone you can deactivate it remotely (and no waiting for replacement credit cards to come in the mail).
The technology goes beyond buying stuff though. You have seen electronic boarding passes for airplanes; NFC will make it even easier. Boarding a train or bus? No more paper ticket needed. Concerts, theme parks, and anywhere that requires admission will be able to be accessed with a pass of the phone. Even something as simple as keeping track of church attendance, or making a donation to the offering plate (or more aptly the offering NFC pad), will be even easier.
Near field communication has huge potential, and it is just now getting off the ground. The biggest hurdle? Getting people to trust new technology. With every new advent in technology there is potential to have it abused. The key is to not be frivolous with your phone. And remember, if you don’t want someone “swiping” your data, just turn the phone off.
