If you have logins, the app TOKEN (on iphone, not sure about android) - just strict about using phone number for verification. Has to be a real number, doesn't have to match account.
There's also the app OXYGEN mobile banking, which is pretty simple to connect account to. I haven't attempted that one yet to know of any tricks.
Personally, I would just make a really great looking check. I would have a Regions bank on hand (easy to obtain, as long as you fund it). And then you have immediate access to mobile check deposit. Regions gives you the option to deposit next day for free, or immediate access to the full amount minus a fee. I have a had a lot of success with that. (Note 9pm EST cut off for mobile deposits).
Just don't keep trying a lot, or you'll lose it.
