Your company seems really interesting, and I'm considering setting up a merchant-account, but I'd STRONGLY advise you to drop the bank login feature. I know it took a lot of code to write. And I know you convinced yourself it's an advantage. But it's not. It's making people run from your site. Look at the comments here, and these are from FRIENDLY people. Many many many others will see that in your blog article, and decide not to sign up for an account, and you'll never even know. They won't write an article, they won't email you, they'll just decide you're skeevy, and abort. You're already working with one tech that people thing is a bit "iffy". That means you need to do EVERYTHING POSSIBLE to make EVERY other bit of your service seem 10,000% above board. Asking for bank login credentials, EVEN AS AN OPTION, torpedos that. You're probably thinking to yourselves - "Maybe we should make the Credit Card primary, and make this secondary?" Just don't. I know you spent a long time writing this, and I really wish it were a good idea, but I'd really suggest you just comment out the feature. You can always put it back in a year or three if you really really want, once your service has inertia, and is already more trusted. But even if Square or Stripe asked for that, it'd scare people away, and lose customers. It's just a bad idea right now. I want you guy to do well. Please kill that feature.
