A card case is the answer to the question of how little is enough. Six to ten cards, perhaps a folded bill — nothing more fits inside, and nothing more is intended to. In return, it doesn't add bulk to your jacket or shirt pocket.
All cases here have RFID protection. Those who also want to carry coins will find the right models among the wallets; those who prefer a mechanism that fans out the cards, at the ClickWallet.
