We love to hear customers enjoying their Verizon Credit Card perks ibclare. I'm sorry you can't find your digital wallet. The Apple Wallet (digital Wallet) is an app on iPhone and Apple Watch that organizes your credit and debit cards, transit passes, boarding passes, tickets, etc. You can try going to Settings.>Tap Wallet & Apple Pay>Scroll down to Allow Access When Locked and toggle on Double-Click Home Button. After adding your card to the app wallet click the home button when you're ready to use Apple Pay for that card.
I hope this was helpful.
