DUKPT DES encrypted pin block, retrieved from a PIN pad.
A 16-byte encrypted PIN and associated KSN (Key Serial/Sequence Number) are required for all debit Sale and Refund transactions. These values must be retrieved from a certified DUKPT DES pin pad device.
Debit transactions are only supported for Retail merchants, and only for Card Present transactions. If you set the UserId to an ID associated with a Direct Marketing or E-Commerce merchant account, or otherwise attempt a card-not-present transaction, the component throws an exception.
