Today I learned, from Kat, that the Digital Credit Union has an iPhone/iPod app! The DCU website needs to learn this from Kat, too, since they still claim to be working on it. Whoops.
This app has a check deposit function! Which is great, because even with the hints I have learned and posted here, scanning checks with the DCU desktop thing is just way too obnoxious and time-consuming and plain old broken. I’ll let you know how it works from the iPhone when I next have a check to deposit.
