If you still have your current card, then you're all good to go! The pass electronically updates the barcode assigned to your card.
Another option you have is to access your pass digitally. You can do this by logging into your account at guest.sevenpeaks.com. Once you're in your account, you can click on My Digital Passes to view each pass. In order for this to work, you need to have pictures uploaded onto your account.
If you lost your card, if it's damaged, or the photos are largely out of date, then you may want to get a new card printed.
