Apple also has specific guidelines for how to store your Apple Card to avoid this type of situation. The company says you should store it in a wallet, pocket, or bag made of soft materials and warns against keeping your titanium credit card in pockets or bags that contain keys or loose change.

Apple also suggests placing it in a billfold where it wouldn't be touching another credit card, since doing either of these things could potentially scratch the card.

That raised some concerns over how practical and convenient it is to carry around the Apple Card.

And of course, some Twitter users were quick to poke fun at the guidelines.

If your Apple Card does happen to get dirty,  the support website instructs you on the proper way to clean it.  The page notes that the Apple Card should be cleaned with a soft, slightly damp, lint-free cloth, and Apple advises using isopropyl alcohol.

It's also important to remember that the Apple Card is free. If it does get scratched or damaged, you can order a new one free of charge and continue using your digital card. But you'll be restricted to only using your card digitally while you wait for your new card to arrive. And if you do want to use it at a brick-and-mortar location, you'll have to make sure it accepts Apple Pay. Apple said in January that 65% of all retail locations in the United States support its mobile payment service.
