How Can I Enable NFC Functionality in an Apple Wallet Pass?

Hello,

I am working on an Apple Wallet pass with NFC functionality but have been facing issues with getting it to work. The pass gets added to Wallet, but the NFC feature does not seem to activate.

Could someone provide a detailed, step-by-step process to properly enable NFC in an Apple Wallet pass? 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).

2. Adding the NFC Field:

• Added the following nfc field to my pass.json file:

{
  "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"
  }
}

3. Tested the Pass:

• The pass is added to Wallet, but NFC functionality is not working.
• When the nfc field is removed, the pass works fine without NFC.

Questions:

1. Could you provide a comprehensive list of required steps to enable NFC in an Apple Wallet pass, including any specific details on encryption, payload, and public key formatting?

2. Are there any additional configurations or settings that I might be missing?

3. Is there any official documentation or specific tools recommended for testing NFC-enabled passes?

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

Thank You
