I use a distributed carry approach to carrying the items I’d normally carry ina bifg fat wallet.
1: a Ti money clip for all bills and other foldable papers
2: an All-et paper thin credit card wallet – for credit cards, essential membership cards and drviers license. I also have printed most of my membership card info on a single laminated sheet I carry in the All-et. I can fit more than a dozen membership no’s on one summary card and leave the bulky cards at home.
