Flat or wallet-style format, banknote pocket, anti-RFID shielding: our card holders are chosen based on the number of cards carried each day and the thickness of the leather, which determines the size in your pocket.
A card holder is chosen based on the number of slots and the thickness of the leather: the thinner the leather, the flatter it stays in your pocket. Our category includes flat models and models with a flap, with or without a bill pocket, made from cowhide, grainy leather, or canvas.
Count the cards you carry every day, not the ones in the drawer. A four-slot format keeps the card holder flat in your front pocket; beyond that, the thickness doubles and it takes up the same space as a wallet. A men's leather card holder the size of a bank card can fit in a shirt pocket, which a wallet cannot. Make sure the slots are lined; a single leather slot stretches and will eventually let the card fall out.
A flat card holder slips into an evening pouch where a long wallet won't fit and often serves as a secondary holder for loyalty cards. The flap models add a pocket for folded bills, while the flat models stick to the bare minimum. The grainy leather withstands abrasion from a set of keys better, while smooth leather ages faster but leaves marks.
An anti-RFID card holder includes a metal sheet between the slots, designed to block remote reading of a contactless card. The shielding only works on the cards stored inside, never on those left in an outer pocket, which is a limitation that product descriptions often forget to mention. An anti-RFID card holder is still an ordinary card holder; the protection does not change the number of slots or how it's carried.
