Minimalist Wallets (sometimes also called "Slim Wallets" - but they're not always the same thing) are even better.
You can hold ALL your needed cards and even some cash (if you actually still carry cash around..) and it takes up way less space - you can literally just fit them in either your front pocket, or better yet, the small extra front pocket present on almost all pants (the one that we never seem to actually make use of, despite it being there).
The Radix One is one that's a really great one, very slick, modern, sleek and easy to use (here's a non-affiliate link to it on Amazon) - I have nothing to do with them, it's just a nice wallet.
Get one and never look back. Seriously. You'll wonder why you lugged around a bulky, clunky wallet all those years. It also has the bonus feature of being way less likely to be pick-pocketed since 1) pick-pocketers generally aim for traditional wallets, which are generally in your back pocket, and 2) somehow managing to pull these minimalist wallets out of your small pocket without you noticing would be much harder to do (they'd have to get right in front of you, generally lift your shirt up a bit, and pull it out of a front pocket which has a higher tension band/seam going into it).
You'll also stop fading and wearing down your pants where your old wallets used to be.
I just have one of those sticky card holder thing that goes on the back of your phone. I also have this and I quite like it as well.
