Google assured users of its smartphone wallets that the mobile-age technology thwarts thieves better than old-school cash or credit cards.A Google Wallet feature that lets people load prepaid card information in smartphones for spending was re-activated this week after being shut off for a few days to fix a potential security vulnerability. The action from Google came after a Zvelo Labs researcher demonstrated software that quickly figures out a Wallet personal identification number (PIN), provided the crook has the smartphone. Security specialists advise Google Wallet to enable security features such as full-disk encryption and screen locks. Google Wallet uses a near field communication chip embedded in a phone to allow a user to "tap-and-pay" for purchases at a checkout register equipped with the PayPass system from CitiMasterCard.
