So basically ... Put in a non chip card let them see it's a non chip card then quickly switch to the actual chip card with the tracks written on that cards magstripe and then swipe .. because the cashier or whoever is allowing a magstripe swipe ? Right ?Actually many pos machines can even work with one insert before swipe even with normal non chip card, just have to be fast and play stupid.. "oops sorry I forgot tjis card has no chip on it"
