LPT: if you have two credit cards, don’t put them both in the same wallet.
The day you can’t find your wallet is the day you need access to a credit card. Also - if you lose your wallet (like some else may have it) you don’t have to cancel both.
—-edit—-
To be sure - you don’t carry two wallets. You keep an extra card at home or a safe place.
And to the “just pay with phone” you might get both stolen. If someone is stealing an unsecured wallet they gon grab your phone too. #entertainment
