How does the card issuer know that the supplier has agreed to accept virtual card payments?

Either you or your card issuer might negotiate with the supplier to accept virtual cards as a form of payment. If the issuer is campaigning suppliers on your behalf and the supplier agrees to accept virtual cards, then the issuer will maintain a supplier record indicating that the supplier accepts virtual cards. In either scenario, the supplier record will need to be updated in Oracle Cloud ERP to reflect virtual card as the preferred form of payment with the associated terms.
