Google Wallet and other similar mobile payment apps will surely shine a new light on mobile security in general, as well, since more and more users will be storing sensitive payment information on their devices, and thieves will have more incentive to hack or steal them.

But it may take a while for the average consumer to be able to use Google Wallet or other similar services, since NFC requires a specific hardware chip and most modern smartphones do not yet support the technology. Google Wallet is also expected to be available only to Android users, at first, so other smartphone owners may not get access to this specific mobile payment service.
