People are talking about NFC, but the things they're saying are generally wrong. NFC is exciting technology, but not for the reasons people think it's exciting.
NFC stands for "near field communication." It's a wireless technology similar to Bluetooth, but with a much shorter range about an inch and a half or less. That short range is the key benefit. A wireless technology very short range means that you can control what you connect with, without having to plug anything in.
Here's what you need to know about these three letters and how they're going to change the world.
Google is expected to announce tomorrow a mobile payment system, as well as some partnerships with companies that support that system. Companies include Sprint, Mastercard, Citibank and VeriFone (which makes the machines that can read NFC chips), as well as retailers like Macy's and American Eagle Outfitters and Subway. The payment system is expected to be rolled out in five cities: New York, San Francisco, Los Angeles, Chicago and Washington, D.C.
So if you live in the right city, and have the right credit card and shop in the right store, you'll be able to use Google's system if it occurs to you do so.
That's exciting news not because it ushers in the NFC era instantly for everyone, but because it's a real first push into that ushering. Google deserves credit for pushing forward while everyone else holding back.
NFC has been around for a while. What's new is that we're reaching the bend in the hockey stick for NFC growth. Like electricity 100 years ago and the Internet 20 years ago, NFC is a technology that has been around for awhile without affecting people's lives, but that will spark a thousand revolutions that will change everything.
But for the average consumer out there, NFC isn't going mainstream suddenly or soon. The technology will creep into general use slowly over the next five years.
Right now business people still practice the barbaric ritual of exchanging contact data on slices of tree pulp. The human has to later read the data and type it in to a contact database, or scan it and hope the optical character recognition software doesn't make a mistake.
NFC will enable people to simply bump phones together and have their contact information exchanged in both directions.
