Do you have any data on conversion rates? I imagine they would tank through the floor if you're asking a customer to turn over their online banking credentials.
Nope! Conversions are pretty good, same abandonment as CC's right now, and it's rising as we get our UX better. People hate inputting their CC information, and when they've heard of Knox at least 1 time before, they're way more likely to convert than using a CC. However, first time users are about the same conversion as CC's in our betas.
