Related question - how do people manage to get by w/ carrying few enough items to only use a small card case? I have wanted to move to this approach for some time, but find I have too many essential things to carry. I do fit it all into a very compact RL wallet made of a black watch plaid vinyl I think w/ leather lining. that has a separate money clip built in. It's lasted me over 10 years. Anyway maybe I'm too complicated to get down to few enough items to go any smaller. I've got drivers license, 2 debit cards, 1 Amex, 1 Visa, Library card, Y membership card, corp ID, health insurance card, car insurance card, plus cash.
