There are a few reasons that checks may not be able to be deposited: Folded or torn corners Front image is not legible Amount entered does not match the amount read by the scanning software Routing and account numbers are unclear No camera on the device Image is too dark Helpful tips for Mobile Deposit: Use Mobile Deposit in a well lit area to prevent shadows or poor image quality when taking pictures of your check. Smooth out any folds on your check. Place the check on a dark background before taking the picture. Keep hands clear of the check while taking the pictures to avoid pictures of fingers/hands. Once your deposit has been posted, we recommend that you securely store your check for 30 days and then destroy it.
