Verify iCVV - AWS Payment Cryptography

Verify iCVV

Example

In this example, we will verify a iCVV for a given PAN with inputs of Key to Use for validation (CVK), PAN, a service code of 999, card expiration date and the iCVV provided by the transaction to validate.

iCVV is not a user entered value (like CVV2) but embedded on an EMV card. Consideration should be given to whether it should always validate when provided.

For all available parameters see, CardVerificationValue1 in the API reference guide.
