MetroPCS customers are now a part of the Google Wallet family

With ISIS – the NFC payment system backed by Verizon, AT&T and T-Mobile — finally making its oft-delayed touchdown, Google has hinted that it’s bringing some changes to its own mobile payment solution, Google Wallet. It’s still unclear what the new version of Wallet will offer, but one thing is clear: Google is ready for the war ahead by expanding its customer base.

As announced on its Twitter account, MetroPCS subscribers can now use Google Wallet on their device. For now, only those sporting the Samsung Galaxy S3 can start using the mobile payment service.

To get started, you have to download the app from Google Play. You can then add any credit and debit cards from Visa, MasterCard, American Express, and Discover to your account. Finding stores and merchants in your area that support the payment system may prove to be the harder part about using Google Wallet.

Nevertheless, the future looks reasonably bright for Google’s payment system, as its user base continues to grow. We look forward to see what improvements the refreshed Google Wallet will bring to the mobile payment table.
