Aha! Multifactor authentication is an integral part of the service. That's a USP. You should put it right in that FAQ. A number of Internet banks used to say "hey, you could mail us checks, or you know, just keep a brick-and-mortar account open and transfer them over." The way the FAQ reads to me is that Simple are a bit bloody-minded about it, what if I never get checks? (I must have had about 2 or 3 this year, total). Then I wouldn't need a smartphone, but Simple would still not let me sign up. Saying things like multifactor authentication would help push the idea that the smartphone is really required, rather than just something helpful.
