I've never understood how the hell Square does it. It's an awesome experience though.

  They (ab?)use the transaction that occurs when money is refunded to a debit card. http://jonbwhite.tumblr.com/post/66853226398/how-square-moves-cash http://jonbwhite.tumblr.com/post/66853226398/how-square-move...

    I was wondering how they did it - that's really cool. Thanks for the link.

    Well I knew that they used the refund rails, but I was curious how they protect against fraud. This seems to imply that there's nothing magical regarding the anti-fraud: they just try stay on top of it.
