The problem with banks, you see, is that they're one of the few remaining weak links in our ultimate goal of eliminating all human interaction. If you've got a check you need to deposit in your account, you've got to trek all the way out to your local branch; sure, granted, you can slip the check in an ATM, but your odds of encountering another living creature in the process of doing that are nonzero. Fortunately, USAA -- which counts military personnel as a significant percentage of its customer base -- is helping to close that loop with its "Deposit@Mobile" service, a component of its just-launched mobile banking app in the iPhone's App Store. The secret, you see, lies in the iPhones magical camera which can "take" a "picture" of the check, transmit it to USAA, and boom -- your cash is instantly deposited. No muss, no fuss, and no pesky people to get between you and your hard-earned cash. Of course, that doesn't change the fact that you've got to get the check from someone in the first place... but, you know, one thing at a time.
