The most convenient and easiest way to deposit a check, once you get the hang of it, is to use your smartphone. Many banks have mobile apps that allow you to use your phone’s camera to snap a photo of the front and endorsed back of the check, type in the check amount, and tell the app which accounts to deposit the check to.
Making deposits online follows a similar process, except that you’ll need to scan your checks or transfer photos of your checks from your camera or smartphone to your computer before you can upload them. Your bank will let you know how long you need to keep the paper checks. After that time has passed, you can shred them.
