I still have an old billfold wallet for when I travel international and want to have local currency, otherwise I used to carry a real minimal wallet like Tin's link to hold ID, one credit card, emergency $20, and a flex spot for wherever I'm going (grocery store loyalty card, library, Costco, ATM card). Currently, I use a Ridge knock-off called Rossm that works well to hold more cards (can carry 12, I only need 6-7) now that I use different cards for different spending bonuses. I always carry in front pocket, and I'm not yet a fan of bringing out the phone for mobile wallet use.
