        I think the practical limit would be 4, for each of the orientations the card can go into the reader.

            Possible, but we’d have to see the reader. The ones I know for transport systems are not the swipe type, but the put card in a slot type, so it needs to stay the same size or get lost in the innards of the machine (don’t ask me how I know… I was young).
