KSN Property

Clear-text Key Serial Number retrieved from a PIN pad.

Syntax

globalbenefitcontrol.KSN[=string]

Default Value

""

Remarks

A 19 or 20-byte Key Serial/Sequence Number (KSN) and associated EncryptedPIN are required for all debit Sale and Credit transactions. These values must be retrieved from a certified DUKPT DES pin pad device. A 20-byte Key Sequence Number consists of a 1-byte pad character ('F'), a 9-byte Base Derivation Key Id (BDK ID), a 5-byte device Id, and a 5-byte transaction counter. If this property is set with a Key Sequence Number less than 20 bytes in length, the control will pad it on the left with 'F' characters.

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 control fails with an error.
