One of the coolest (and hence, most hyped) uses of NFC would have to be the use of it for contactless payments.Just like your MasterCard or Visa card with PayPass or payWave.
The most widely known example of using your phone as your wallet is probably Google’s Wallet app. After installing it on your Android phone, you’re all set to tap away.
But the problem with Google Wallet is that Google wants to control the whole experience, so you can only install it officially on a handful of devices, has only integrated tightly with Citibank, and so only a handful of customers can actually use Google Wallet.
Thanks to the internet however, it’s possible to shoehorn Google Wallet on to devices that aren’t ‘technically’ supported and tap away.
Since grabbing my Galaxy Nexus, Wallet was one of the most exciting things I was looking forward to trying, and surprisingly getting it going wasn’t much effort at all.
