Last month, Google Wallet for Android got an update that allowed capturing credit and debit card info via smartphone camera. Now, that functionality has arrived for iOS users. That's right, you can now use that iPhone to snap an image of your plastic arsenal in order to organize that digital billfold. The app also plays nice with other Google apps that support single sign-on now too, so when you log-in to Gmail, this list of other software you'll be signed into automatically includes Wallet. And if you've opted for a physical Wallet cards, you'll be able to spend or withdraw from your iOS funds repository with that piece of plastic as well.
