The Google Prepaid Card is a virtual MasterCard account designed for use with the company's near-field communication Google Wallet payment app. Users that activated the "card" when it was released in 2011 received a free $10 credit for use with the system.

To prompt users to spend all the remaining money on their pre-paid accounts, Google announced that it would charge a $2 fee for 30 days of inactivity, though the company also noted that no fees would be levied on accounts that had zeroed out their balances by Oct. 17.

This is likely a move by Google to minimize the amount of manual refunds they will have to issue for anyone who still has a balance after the deadlines, as is the company's announcement that such direct refunds could take eight weeks to process.

All other types of cards will continue to work normally with Google Wallet after the change. Google added support for Visa and Discover last month, though initial reports that American Express had also joined the program .
