Slight tangent, but I'm pretty sure sending money to phone numbers is pretty much how 90% of banking in Africa gets done, it seems like pretty cool stuff. Also, I have a bank account with PNC, and if I need to send money to a friend, all I need is their email address, and PNC sets up a transfer, and shoots them an email with a link and instructions for retrieving the money/depositing it into their (not necessarily PNC) bank account. Also the whole cashing a check via taking a photo on my phone is a pretty awesome feature.
