I don't get how you can end up with so many cards, it's seems like a very american problem. I have 5 cards in my wallet:
* Debit card and a Visa credit card: both with chip&pin and allowing me to do secure transaction on the internet
* A public transport card: RFC, also allow me to rent bikes
* An ID card, also with a chip&pin, allow me to sign documents and fill my taxes
* An insurance card which is not even a magnetic or electronic card, it's just a piece of plastic with my client number printed on it
And I don't really see why I should need or want more cards
