## Discussion

This property contains the data provided to the payment network as a cryptographic one-time pad (OTP), per the Payment Network API specification. The cryptographic OTP is not interpreted by Apple or iOS. The OTP should be verified by the issuer and/or payment network upon receipt of the provisioning request to ensure the request’s authenticity. For more information about the activation data’s content, contact your payment network.

> Note:
> This is the same type of activation data that is accepted by the pass library’s ``doc://com.apple.passkit/documentation/PassKit/PKPassLibrary/activate(_:withActivationData:completion:)`` method.
