I've been saying this for 10 years. Pull the card in horizontally instead of vertically and read it inside the machine. Skimming problem solved.

This presents a non-trivial UI problem. Users are conditioned to only insert cards a certain way. Changing that can be very confusing. I guarantee a large percentage of users will try putting their cards in the "normal" way and get confused when it doesn't work.

Someone at Diebold had the same idea, apparently quite recently: http://news.diebold.com/press-releases/diebold-stops-atm-fra...

Can't be done. They would have to change the arrows on all the cards... ;)

What do you mean?
