We are essentially implementing a membership card feature wherein the card details originates from a third-party provider and gets stored in the Apple Wallet. We are utilizing the Passkit Generator ( https://www.npmjs.com/package/passkit-generator ) for this purpose. The challenge, or rather issue, is that when this card is saved to Apple Wallet and tapped on the NFC reader, it only shows "Invalid Card." When we attempted to gather information from the third-party provider regarding this issue on both Android and iOS, they stated: "For IOS we do not have any experience to share with, rather than the fact we have implemented the VAS protocol under an NDA signed with Apple. Related to Passkit we do not have any experience with it." We require your assistance to identify any potential issues.
