I've just come across this ad for Lloyds bank , where you can upload a picture and have it printed on your credit card.

Seems to me that this opens up a lot of territory for the resourceful magician, a carefully put together pic with several 'outs' would be useful, a full card face, or maybe just a pic of yourself with deck as talking point/advert.
I dont know if other banks do a similar service, but thought I'd throw the idea in the ring.
