About 15. And sure, most I barely use. But sometimes I want to use them and they're in my bag and not in my wallet. This would be a great solution to that problem for me if it could hold all of them.
I have a money clip, and only carry my most pertinent cards - ID, ATM, and CCs. The remaining cards, like reward cards or library cards, are in a tin can in my car - which I drive to wherever I'm shopping, and just remove the card I need. I can't imagine carrying 15+ cards in my pocket, especially if it is in your back pocket.
I carry around the following:
1 Debit card
1 Credit card
1 Drivers license (usually I travel with public transport, but I'm required to carry an ID by Dutch law)
1 Ov chipknip (card for public transport in the Netherlands)
1 Health insurance card
2 Loyalty cards for competing grocery stores (I attend both of them on a regular basis)
Even though Coin doesn't solve this problem, especially since it doesn't have EMV which is required in Europe, I'd love to have all off them one card. I have another boatload of cards at home that are rarely / never used because I never have them on me when I could use them.
So basically: very cool idea, needs some more thought for the european market though.
