Card holders aren’t a common thing for most people, wallets are. However, did you realize how many cards do you really use on a daily basis? Credit cards, identity card, driver’s license and some banknotes will get you through the day. Nowadays, a smartphone will do fine for paying bills and making any purchases outside. If that’s all you need then that will reduce the weight and bulk a wallet gives you.
For business people who constantly need to hand out business cards, a card holder will reduce those awkard moments trying to pull out a business card from your wallet. Quickly pull out one and hand it out to show how efficient you are.
