The contents of your wallet are under attack. Earlier this month Coin swept in threatening to eliminate the need for all of your beloved non-cash payment methods and now Google Wallet is making it even easier to capture your plastic with its latest Android update. Along with the introduction of its very own physical debit cards, Google added the ability to upload your debit and credit cards to Wallet by simply snapping a picture with your smartphone -- similar to the recent addition to the Dropbox Android app. Instead of entering your card numbers manually (such a drag, we know), those users who see a camera icon in the "card number" field of the Wallet mobile app, can capture both the card number and expiration date with a photograph.
