I have the zippy mulitcartes and I like it. It actually does fit a lot. I put my license and cards I use daily, which is very few. Most are just loyalty and insurance cards. You can double up your cards too. Right now I have about 13 cards, stamps, some other little papers and cash in it right now. Of course you have to fold up your cash. The cash part is a little more annoying to me though as I don't really like folding it up. But it doesn't bother a lot of other people. I also have the Toiletry 19 pouch. I don't use it very often but I think it would also work well as a catch all in larger bags. And you could also just go with a standard card holder or 6 key holder. The card holder are very thin, but also limited with how many cards you can carry.

And for reference the Zippy Multicartes will fit in the Toiletry 19 sideways and upright. I could also fit my phone but I used it to take the picture. Works great as a small clutch. Maybe I really should use my Toiletry 19 more often!
