i could not get past the fact the guy is dancing like he has to pee like there is no tomorrow.

did not see what you are talking about.

but yes, your cards can get scanned even in your wallet.

CC readers are the least of your worries. every time you order something over the internet and use your CC someone has access to ALL the info they need to use your card. even that super secret private 3 digit code on the back that really makes CC more secure.
it has happened to my wife several times now for her business.
she narrowed it down to this one company she orders from. every time she orders from them her card gets "stolen"
fortunately the banks are eating the loses. I think you would be pretty hard pressed to find a bank that does not cover their CC getting stolen.

we have these cards that go behind our ID badges for work so no one can scan our badges. you can get the same thing for your wallet. I could see someone in a big city that rides subways or is in large crowds wanting one.
