Currently one of the only ways to shop with NFC is to use Google Wallet, which is only available on the Nexus S. Thanks to Paypal, you'll now have your own way to receive money from a friend just by bumping phones. Paypal 3.0 for Android has just added support for NFC payments. First you'll need to have the request money widget. Then you enter an amount you wish to give or receive, and then tap phones with another lad who also has an NFC equipped Android device. Your friend then has to enter his password and the transaction will be completed securely.
