How to Create an NFC-Enabled Wallet Pass with pass.json Including NFC Field?

Hello,

I’m working on creating an NFC-enabled Apple Wallet pass and I need assistance with the proper implementation of the pass.json file to include NFC functionality. My goal is to enable NFC interactions, such as tapping to unlock a door or interacting with other NFC systems.

Here is what I have done so far:

1. Set up a Pass Type ID and Certificates:

• I have registered a Pass Type ID in my Apple Developer account.
• I have generated and installed the required certificates (Pass Type ID certificate and WWDR certificate).

1. Backend Integration:

• I have set up a backend service for generating passes, and I can successfully create and deliver standard Wallet passes without the NFC functionality.

1. Adding the NFC Field:

• I understand that to enable NFC interactions, I need to add an nfc dictionary to the pass.json file.
• The key components for NFC include the encryptionPublicKey, message, and payload.

Here’s an example of my current pass.json:

{
  "formatVersion": 1,
  "passTypeIdentifier": "pass.com.example.mypass",
  "serialNumber": "123456",
  "teamIdentifier": "TEAMID12345",
  "webServiceURL": "https://example.com/api/passes",
  "authenticationToken": "my_secure_token",
  "nfc": {
    "message": "Tap to unlock door",
    "encryptionPublicKey": "MY_ENCRYPTION_PUBLIC_KEY",
    "payload": "encrypted_nfc_payload"
  },
  "organizationName": "My Company",
  "description": "NFC-Enabled Access Pass",
  "logoText": "My NFC Pass",
  "foregroundColor": "rgb(255, 255, 255)",
  "backgroundColor": "rgb(0, 0, 0)",
  "barcode": {
    "format": "PKBarcodeFormatQR",
    "message": "https://example.com",
    "messageEncoding": "iso-8859-1"
  }
}

Questions:

1. Are there any additional steps or configurations required to ensure that NFC is enabled in the pass?

2. Is there a specific method to test or validate NFC functionality in the pass to debug why it’s not being activated?

Any guidance or solutions to enable NFC in this pass would be greatly appreciated.

Thank You
