Wells Fargo has released Mobile Deposit in the Wells Fargo Mobile app.

What a great idea! No need to go to a branch or even an ATM.

Its Deposit Usage guidelines include the following:

• Mobile Deposit users are required to retain the original paper items in a secure place. We also recommend you write on the front of the check: “Mobile deposit on DATE” (where DATE is the full date you deposited the check by Mobile Deposit).
• Mobile Deposit users are required to retain the original paper items, for a minimum of five (5) calendar days, but no longer than fourteen (14) calendar days, after they have been transmitted to the Bank
• After the retention period, the original paper items are required to securely and irretrievably destroy the original paper items so they are not deposited again.
