I second the recommendation for the secrid wallet. I used to carry around a thick heavy wallet jam packed with all my ff/loyalty cards, I managed to condense it down to 5 cards (debit, 2 credit, commuter pass, main loyalty card), along with driver's license, health insurance cards, and a bit of cash that discreetly fits in my front pocket. The rest of the loyalty cards went into a card holder that stays in my briefcase. With the flick of the lever, my primary debit card pops out enough to allow me to tap for the debit machine. I might condense things further as I use Apple wallet more with my iPhone. Extremely pleased!
This is the one I got, but in black leather:
