Seems crazy that it only holds 8 cards. I'm not about to go through all this effort only to replace some of the cards in my wallet but not all of them.

Most of the cards in my wallet aren't credit/debit cards anyway. Drivers license, health insurance, etc. etc.

This wouldn't be able to replace my wallet, so I'd still be carrying two things around with me.

Out of curiosity, how many do you have? I think 8 would cover all of the cards I use at least once every 4 months.

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.

I guess it depends on how many cards you have. I suspect it's also a limit of the first run costs, and could increase in future.

Personally I only have one card, so I don't really have that problem :D

The app holds infinite cards, as long as you carry your phone.

Yeah, pretty easy to just store all cards in the app and switch out the infrequently used cards for things like loyalty programs when you actually need them.

If you do that the battery runs down faster, and since you can't replace the battery or charge it, once that happens you are out $100.

I was really thinking of buying one but $100 every two years is too much for this.
