Great ideas tend to make so much sense that you wonder why they took so long. Here's another: USAA, a privately held bank/insurance company, is updating its iPhone app to let customers snap both sides of a check for deposits.
The bank's VP tells The NY Times that once you hit the send button, the deposit is made just like any other check—you won't have to mail it in later, either. As everything will be handled electronically, the bank will suggest customers simply void the check before either filing or discarding it.
The Times does point out that the capability will only be available to customers who are either eligible for credit, or have some type of insurance through the bank, but I gotta tell you—if my bank had this, I'd definitely use it. Being able to deposit at the ATM is one thing, but this screams convenience.
