I have learned that the Digital Credit Union iPhone app works like a charm for check deposits right from the phone!
It took me a few lessons to get here. One was that there was a PC deposit function that looked like it worked, but only sometimes. Then Kat told me about the iPhone/iPad app that was not announced but out there and great for checking balances.
Now it’s come together in this free thing.
Once logged in, click which account, enter check amount, photo of front, photo of back, DONE! Worked like a charm on the first try. Wow.

Nice!!
And yet we still need an option for those of us who don’t have iPhones, and it shouldn’t require a scanner! Grrr.
