This idea already was used here in portugal... But didn0t have much success... after a year or so it was hard to find a store that accepted your cards.
But hey! we also were one of the pioneers (if not _the_ peioneers) at introducing "Multibanco" (ATM), "Via Verde" (highway payment system)...:D
BTW: here was called "Porta moedas Multibanco"...
