Here is a link to the account you’ll want: It’s called the Investor Checking Account.
It requires that you start an investment account, which you don’t have to actually use and has no fees to have. Their bread and butter is investment management, and the checking accounts are largely an attractive feature to help people make the decision to use their other services.
On one of our account groups there, we’ve never used the investment account at all, other than to initially fund the account.
As far as transferring funds, once accounts are all set up and verified with each other, it’s a simple matter to move money around wherever you are to/from whichever accounts you have. We’ve used only online banking for 3-4 years now, and have not had anything but easy success with them.
The only issue I can see is if you still get checks mailed to you with any regularity, as there are very few actual physical locations to take them, and for the most part, they need to be mailed in.
There is a mobile app I haven’t dealt with much that should have the photo check deposit thing. But I don’t generally deal with checks, so can’t really speak on that much.
