Google is ditching the pre-paid card it gives to people who sign up for its mobile wallet, telling customers to spend any money they have on it by the middle of next month.
The search giant says that the pre-paid card has become obsolete since it overhauled its wallet last month to enable users to link any debit card.
In a notice to customers, it warns that from 17 September customers will no longer be able to add funds to their Google pre-paid card or add a new one to a new phone.
Then, from 17 October, the pre-paid card will disappear from Wallet apps and users will no longer be able to spend the balance, although they can request a refund.
In February Google was forced to disabled provisioning of the pre-paid cards for the wallet after researchers found a number of gaping security holes in the application.
