Brilliant solution, but can anyone tell me how they avoid fraud? I just sent money to a friend, and back. It worked fast and flawlessly, as expected. Supposedly money will be posted to my account in 24-48 hours. All good there. Now, how can they make sure that the email is genuine and wasn't spoofed? Sure, they can check for white-listed domains and SPF records, but still seems fairly weak process. The FAQ [1] doesn't say much either. Human validation is even worse. It helps that the send receives an email confirmation with the transfer, but you may not check the email before the money is posted. I guess they're pushing the onus of the proof to the receiver -- after all to receive the money you have to have a bank account and a visa/mc debit card. Whatever the security mechanism, it's a brilliantly simple solution. If it takes off, it'll quickly replace Dwalla and other micropayments.
