While Passbook is a great way to manage loyalty and payment cards, it can start to get cluttered after a while. That's why it's a good idea to clear it out here and there. Perhaps you have loyalty cards you never actually use, or you've replaced one card with a new one. Whatever the reason, deleting cards from Passbook is just as easy as adding them in the first place.
The card you deleted will no longer appear in your Passbook.
