It was back in May, at an event shortly after Google I/O, that we first gota look at Google Wallet. The service, which aims to be a replacement for your existing cards rather than an accessory to them, is rolling out in New York, San Francisco, Los Angeles, Chicago and Washington, DC and you can get started atthe Google Wallet site.

Google Wallet works via near-field communication (NFC) which means that you’ll have to have an NFC-enabled phone in order to use the service. At the moment, that means that you’ll need a Nexus S. Fortunately, the S is available across a few US-based carriers, so it’s not an impossible hurdle to cross, but only the Sprint version works with Google Wallet for now.

Google tells us viaa blog postthat it’s expanding past its original Citi and MasterCard limitations, too:

We appreciate Citi and MasterCard for being our launch partners. And today, Visa, Discover and American Express have made available their NFC specifications that could enable their cards to be added to future versions of Google Wallet.

For those of you worried about security, Google tells us that your card information will be stored in a single place, on a chip. That means that it should be at least somewhat firewalled from unauthorized software access. However, there is another failsafe that limits new cards to $100 until the owner releases the limitation so that should help to quell any fears.

Google is betting big on NFC over the next couple of years, stating that nearly half of all smartphones should have included chips by 2014. However its delay in entering the space has allowed some agile companies such as Dwolla to solve the lack of hardware issue with a software solution.Dwolla’s Proxi systemallows near-field payments without the necessity for an NFC chip, relying instead on the accuracy of GPS.

For now, Google Wallet is live, so you canhead over, get signed up and start checking it out. Google had said in May that the system was ready for action at over 300,000 merchants, with another 120,000 possible. All that remains to be seen is whether the system will work as elegantly asthis videoshows is possible:
