This should defs happen and no one could break into one so its secure as hell!
What makes you think that?I would be interested, but I would like the OP to give a little more clarity as to his idea as bitcoins are a virtual currency not physical. Are we saying users would have a card and they'd be able to slide the card and based on the current exchange rate transfer X amount of bitcoins to a bitcoin account and then withdraw USD. If so, i'm interested, but currently the US government is going against bitcoin and thus these would probably lead to expensive lawsuits which I am not interested in.
