Checks should be securely stored for a period of thirty (30) days after you receive confirmation from Remote Deposit Capture that your deposit has been accepted.  This provides sufficient time for research in case there is an issue with the image quality or if the original item is required for any other reason.

Do not leave your deposited check lying around unsecured and do not put the deposited checks in trash or recycle bins unless they have been shredded first.  The paper check should be stored in a secure place and should be irretrievably destroyed after the 30 day retention period.  A cross-cut or diamond shredder will assist in complete destruction of the check information.
