I spotted these beautiful card protectors at a trade show last year and they have been on my mind ever since as they are such a good idea.  They protect your credit cards from unwanted wireless communications like card scanning and they prevent your cards from bending and breaking.  I think we could all do with one of these in our pocket.  I really like the simple movement of the mechanism allowing you to select the card you want, leaving the card you use for wireless contact at the back so you don't even have to pull it right out.  This cardprotector holds up to six cards including one embossed card or five cards including three embossed ones.
