Google Wallet announced, NFC mobile payments are now live

Now that Google Wallet has been announced (Google wallet video breakdown,) lets break down how you'll use this stuff. First, Google has a number of partners on board. Companies like Subway, Macy's, Toys 'R Us, Citibank, MasterCard, Walgreens, First Data, and Sprint. The nice thing about MasterCard is that the partnership means that Google Wallet is instantly compatible with all those PayPass NFC systems that you see in a bunch of places. Google Wallet trials are now live in San Francisco and New York City, and should be available nationwide sometime in the next few months.

As far as devices go, the Nexus S 4G is the only phone that will work out of the gate. However, other phone without NFC built-in can likely just use an NFC sticker, making them compatible as well. One pain here is that you must have a Citi MasterCard alongside a Nexus S 4G right now if you don't want anything else getting in the way. If you don't have a Citi MasterCard, and don't feel like applying for one, then you can set up a Google Prepaid Card, which you then have to fund from your other cards. Kind of a pain for now, but these are the necessary steps that need to be taken in order for us to get to the future, right?
