Google Wallet fixes prepaid card security bug
Reacting to recent hacks that could expose a user's funds, Google has patched a security flaw in Google Wallet and reenabled the use of prepaid cards.
Google has patched a hole in Google Wallet that could've allowed someone to access a user's funds simply by resetting the PIN and using a prepaid card.
The company said yesterday it has issued a fix that now prevents a prepaid card from being re-provisioned to another person. It has also restored the ability to issue new prepaid cards following a move on Monday to .
Osama Bedier, vice president of Google Wallet and Payments, said that he wasn't aware of any actual incidents of people abusing the prepaid cards or Wallet PIN, but "we took this step as a precaution to ensure the security of our Wallet customers."

A lost or stolen phone without a screen lock would be especially vulnerable, particularly to the second hack, which could be performed in a matter of minutes.
Google did respond to the hacks in a reasonable amount of time and took the right precautions by disabling the prepaid card access before it created a fix. And the company has insisted that the overall security of Google Wallet is solid, in many ways safer than using a conventional credit card to pay for items.
"Mobile payments are going to become more common in the coming years, and we will learn much more as we continue to develop Google Wallet." Bedier wrote. "In the meantime, you can be confident that the digital wallet you carry provides defenses that plastic and leather simply don't."
Bedier is right in saying that paying for items via your mobile phone will become more common. But so far the technology is off to a slow and rough start.
