Unable to add Card on my Apple Wallet

Re: "Unable to add Card on my Apple Wallet : Will not let me add card"

To use Apple Pay, you need:

• A compatible device1 with the latest version of iOS or iPadOS, watchOS, macOS, or visionOS.
• A supported card from a participating card issuer.
• An Apple Account signed in to your Apple device.

Learn if your country/region supports Apple Pay.

To check if your card is compatible with Apple Pay, contact your card issuer.
