generate_pin_data#

PaymentCryptographyDataPlane.Client.generate_pin_data(**kwargs)#

Generates pin-related data such as PIN, PIN Verification Value (PVV), PIN Block, and PIN Offset during new card issuance or reissuance. For more information, see Generate PIN data in the Amazon Web Services Payment Cryptography User Guide.

PIN data is never transmitted in clear to or from Amazon Web Services Payment Cryptography. This operation generates PIN, PVV, or PIN Offset and then encrypts it using Pin Encryption Key (PEK) to create an EncryptedPinBlock for transmission from Amazon Web Services Payment Cryptography. This operation uses a separate Pin Verification Key (PVK) for VISA PVV generation.

For information about valid keys for this operation, see Understanding key attributes and Key types for specific data operations in the Amazon Web Services Payment Cryptography User Guide.

Cross-account use: This operation can’t be used across different Amazon Web Services accounts.

      Note

      This is a Tagged Union structure. Only one of the following top level keys will be set: PinOffset, VerificationValue. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

      'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

      • PinOffset (string) –

        The PIN offset value.

      • VerificationValue (string) –

        The unique data to identify a cardholder. In most cases, this is the same as cardholder’s Primary Account Number (PAN). If a value is not provided, it defaults to PAN.
