# Pass.NFC

An object that represents the near-field communication (NFC) payload the device passes to an Apple Pay terminal.

## Declaration

```data
object Pass.NFC
```

## Properties

encryptionPublicKey: The public encryption key the Value Added Services protocol uses. Use a Base64-encoded X.509 SubjectPublicKeyInfo structure that contains an ECDH public key for group P256. message: The payload the device transmits to the Apple Pay terminal. The size needs to be no more than 64 bytes. The system truncates messages longer than 64 bytes. requiresAuthentication: A Boolean value that indicates whether the NFC pass requires authentication. The default value is false. A value of true requires the user to authenticate for each use of the NFC pass. This key is valid in iOS 13.1 and later. Set sharingProhibited to true to prevent users from sharing passes with older iOS versions and bypassing the authentication requirement.

## Discussion

Discussion note: Adding NFC to a Pass requires a special entitlement issued by Apple. For more information, see Near Field Communication in Getting Started with Apple Wallet.
