Surcharge Mode
Some networks allow a surcharge, or terminal fee, to be imposed on withdrawal transactions.
If surcharges are in use on your network, you are required to notify the customer of the possi-
bility of an additional fee before the transaction is processed. The customer must be given a
chance to cancel the transaction.
Setting the SURCHARGE MODE to ENABLED will cause the surcharge warning screen to be
displayed after the customer’s card is inserted. The surcharge warning screen notifies the
customer of a possible fee and its amount. The customer is given the opportunity to cancel the
transaction at no charge or to accept the surcharge and continue with the transaction.
If your network does not allow surcharges, the SURCHARGE MODE must be set to DIS-
ABLED.
The amount of the surcharge is stored in the Terminal and displayed to the customer. The
SURCHARGE AMOUNT displayed on the screen can be set manually via the SURCHARGE
AMOUNT menu. In some cases this value is downloaded from the processor at the same time
the communications key is downloaded.
Manually changing the SURCHARGE AMOUNT to a different value does not automatically
change the surcharge collected by the processor for a transaction. It will only change the
surcharge in the surcharge-warning message shown to the customer and NOT the actual fee
collected for the transaction, so be sure the values are the same AND are accurate!

MAC Master/Working Keys
The MAC Master and Working keys are only used if an optional Secure Pin Entry
Device (SPED) keypad has been installed and MAC-ing is being implemented.
The MAC MASTER KEY is used to decrypt the MAC WORKING KEY. Each key is a 16-
character string, consisting of a combination of the digits 0-9 and the letters A-F. The MAC
MASTER KEY may be injected from a personal computer (using a special floppy disk), or
entered manually at the keypad.
