Google announced on Wednesday that its Google Wallet mobile payment app — largely supported by Sprint in the United States — now supports any credit or debit card. I usually refill my Google prepaid card for purchases, but this update is amazing for me as a resident of New York City. Here, I can use Google Wallet at Walgreens to buy nearly anything, or to purchase train tickets in Penn Station on New Jersey transit.

The only device I use with Google Wallet right now is the Nexus 7, so I feel a bit silly holding up a 7-inch tablet to make purchases at Walgreens. However, I’ve also used Sprint’s loaner review units with my Google account for a more normal experience. As an AT&T customer, I’m primarily waiting for AT&T, Verizon and T-Mobile’s competing ISIS initiative to kick into gear so I can use my Galaxy S III for mobile payments instead.

Anyway, I’m getting ahead of myself. Let’s dig deeper.

“Today we’re releasing a new, cloud-based version of the Google Wallet app that supports all credit and debit cards from Visa, MasterCard, American Express, and Discover,” Google said in a blog post. “Now, you can use any card when you shop in-store or online with Google Wallet.” To enter a new card, simply launch the application and type in your credit card number. A transaction record will be stored on the phone and in Google’s online wallet interface.

Google has security measures in place in case you lose your phone or tablet. “We take security very seriously and have always had a dedicated Google Wallet PIN to prevent others from making payments with your Google Wallet,” the company said. ” And as always, we encourage Google Wallet customers to set up the phone’s screen lock — as an extra layer of protection.” However, Google also implemented a brand new security feature that allows you to remotely disable a lost phone so that anyone with access to your pin will be prevented from making a purchase.

The application is now live and is free from Google Play.
