Field help (VERIF) 

Select whether to verify that the payment card is valid.

If Post order is selected in the Authorization step field, a verification that the card is valid can be obtained when entering the order (the name and address match the card number). It will test the validity of the card by processing the verification amount specified for authorization at order placement. If the card is invalid, a decline response will be received placing the order on Declined status.

Selecting No excludes the verification process during order entry.

Selecting Yes will process the actual order value authorization at shipment generation. This process will validate the digits and check that the card has not expired.

This field is available only if the authorization step is assigned to Post order.
