In an official email which Google has recently sent out to the current users of its Google Wallet app, the company will phase out prepaid cards for Google Wallet in the coming months.

Giving the users the deadlines for when it will stop accepting the prepaid Google Wallet cards, Google said in the email that users will no longer be able to add prepaid cards to the Wallet app after September 17, 2012. The company also specified that users will not be able to add any existing prepaid cards which are removed from app after the mentioned date.

Google also said in the email that users of prepaid cards will be able to spend their remaining balance till October 17, after which the company will discontinue its support for the cards altogether. As such, with effect from October 17, prepaid cards will disappear from the Wallet app forever, with all remaining balance to be rendered unusable.

Google's decision to kill off Wallet prepaid cards is apparently a result of the fact that the company's recently-announced changes to its mobile app stores payment cards, under which payment card information will be moved from the device to its cloud; thereby enabling the customers to use almost any credit or debit card.

In fact, Google specified in its email that it had decided to pull the plug on the longstanding prepaid program because it "recently launched the ability to use any debit or credit card in Google Wallet."
