To support all credit and debit cards, we changed our technical approach to storing payment cards. The Google Wallet app now stores your payment cards on highly secure Google servers, instead of in the secure storage area on your phone. A wallet ID (virtual card number) is stored in the secure storage area of the phone, and this is used to facilitate transactions at the point of sale. Google instantly charges your selected credit or debit card. This new approach speeds up the integration process for banks so they can add their cards to the Wallet app in just a few weeks. Banks that want to help their customers save cards to Google Wallet, including their custom card art, can apply here — there is no cost.

We take security very seriously and have always had a dedicated Google Wallet PIN to prevent others from making payments with your Google Wallet. And as always, we encourage Google Wallet customers to set up the phone’s screen lock -- as an extra layer of protection.Today, we’re adding a Google Wallet security feature that makes it possible for you to remotely disable your mobile wallet on a lost phone. It’s easy. If you lose your phone, just visit the ‘Devices’ section in the online wallet and select the phone with the mobile wallet you wish to disable. When you successfully disable your wallet on a device, Google Wallet will not authorize any transactions attempted with that device*. If the Google Wallet online service can establish a connection to your device, it will remotely reset your mobile wallet, clearing it of card and transaction data. There is no way you can do that with your leather wallet.The new Google Wallet app is available now on Google Play , and if you have a supported NFC device and are in the United States, we encourage you to give it a try.Posted by Robin Dua, Head of Product Management, Google WalletQuick tip: lot of questions about the need for Internet connectivity while using the Wallet app. You will need an Internet connection to enter a credit card; to change the selected payment card; and to see transaction details. However, you will not need an Internet connection to actually make a payment in-store if you have previously selected a card.
