Jack Dorsey’s Square Is (Almost) Open For Business – via TechCrunch

I like the idea, but i have the same reservations as many others. The possibility of card cloning / fraud seems too great. I’m sure there are security elements in place.

The security saving grace for me is that they have a photo of you to verify. If i had my card stolen i would want that feature in more shops / stores.

Other than that the service and interface seems really slick…
