While I think the idea behind contact-less purchases is pretty cool, I'm not sure it's the revolution people seem to think it is. I don't believe people will really leave their credit cards at home because they can use the NFC technology in their phone. We'll still have to carry both around because of our government IDs. I can only imagine this technology pissing me off as I wait in line behind someone fumbling around with their phone, trying to unlock it, open the program, pick their electronic card, enter their pin... It'll be almost as bad as those stupid old ladies that use their check books at the grocery store.
At the end of the day, your old-technology credit card will be able to be whipped out, swiped, and you're on your way. No lock screens, pins, or potential of leaving it on the bar at the end of the night. I can't tell you how many times I've misplaced my phone. I rarely misplace my wallet.
The Fast Company article talks about putting NFC in Ultrabooks as well. I can just imagine someone trying to make a purchase with their ultrabook. That seems even more awkward and slow than on a phone.
I can just imagine that I'm out on the town, with all my credit cards at home, and I lose my phone. Now I need to not only purchase a new phone, but cancel my credit cards as well. But if I cancel my credit cards, I can't buy a new phone. But not to worry because I CAN'T cancel my credit cards because I don't HAVE a phone.
I think this technology will catch on eventually, but not until Apple puts it in the iPhone. Google is trying to get the technology going, but not enough of the Android phones have NFC. While millions of Andoid phones are sold each year, there are a 100 different models and only a few (2 I think) have NFC. If Apple puts it in the iPhone 5, then I think there will be enough of a critical mass for merchants to actually start putting the technology at the checkout.
