Don't know if your personal card is an Amex or not, but my Amex is a Costco Amex and doubles as my membership card.

I'm surprised your loyalty cards aren't the smaller key ring ones. I have half a dozen on my keys and barely notice them.

I leave my AAA and Airline cards at home and pull them out when I need them for trips. Could probably do the same for your Zip Car card (unless you use the service multiple times a week or something) and other rarely used cards.

Last year my medical insurance company switched to paper cards which are much thinner and easier to deal with even if they're less sturdy. Same as my car insurance.

All that being said I still walk around with about a dozen cards in my wallet, so I can definitely sympathize. But I could probably edit out 3 or 4 right now and not really miss them.

The problem is any time you edit some of them out, you realize soon after that you don't have the one you need. If I don't carry around the cards I will need every day, I am likely to forget to take the ones I need only occasionally when I do need them.

The problem is that Coin doesn't really solve this. It only encodes credit cards; most of the other cards either don't have mag stripes or require other information on the cards than just what's on the mag stripe.

That happens to me all the time with my airline club cards. I always get to the airport and realize I forgot them.

Ironically, I think my AAA card could double as a AMEX. But I don't use it for that.

I do have a lot of the shopper cards available on key. But I run uber-light on my keys and shifting cards from one pocket to another doesn't really help me gain anything. Also, with the key-ring versions, I've shared them with my S.O. so we can keep all our groceries and loyalty points together so they add up faster for household items or discounted gas, etc...

The problem with leaving a card like Zip Card at home is I'm inevitably going to be somewhere that's not home and need a Zip Car.
