Google's last update to their NFC-powered application on Android, Google Wallet, saw the Mountain View-based company open it up to let users add any credit card they wanted.

Since the company has done this, they've noticed the usage of Google Wallet has doubled. Google have slowly been pushing credit card companies to optimize their own section for the Google Wallet app, too.

The only thing Google need to do now is spread the tentacles on Google Wallet, as the US isn't the only market in the world that needs something like this. I'm based in Australia, and I'd love to be able to use Google Wallet, hopefully we'll see more use of NFC-powered payment systems in the near future around the world.
