I recently left a bank in the midst of considering this only to come to a bank that is figuring out how to implement it. My previous bank was looking at services that ask those specfic multiple choice questions(like, an address that you lived at and one or none of the addresses might be correct) in addition to the customer scanning their ID. Is that enough? I don't know. I didn't think so, but that's more of a gut feeling than anything.
The other issue for me was based around the OCC's MLR and how to record accounts opened by mail/phone/computer. I had a couple questions for the OCC, but never got the chance to ask. Namely,
1. What counts as an account opened online? If the customer has to physically come into the bank and see a CSR (so that the CSR can compare documentation to the customer) before the account can be funded, is it still considered to be opened online?
I don't suppose any of this will help. I've not heard what my new bank is considering. Personally, I hate the whole idea.
