FUNCTION: BLOCK ISO’S

MANAGEMENT FUNCTIONS menu.
2.) Select SET TERMINAL PARAMETERS.
3.) Choose the SURCHARGE MODE option.
4.) Choose the BLOCK ISO’S option.
DESCRIPTION:
This function is used to block surcharging and to disable the display of surcharge messages for
transactions that use a particular financial institution’s ATM or Credit Card. Entering the financial
institution’s unique ISO (International Standards Organization) Number on this screen enables the
function.
The terminal can store up to 100 ISO numbers to block at one time; however, only 5 numbers can
be entered using the BLOCK ISO’s screen. Additional ISO numbers (up to the 100-number limit)
must be downloaded to the terminal using Triton Connect management software.
From 1 to 9 digits may be used. The terminal will compare the card number to all current ISO
numbers to the length of each number. For example, three ISO numbers are entered , including
‘581234’, ‘46’, and ‘3785’. Any card beginning with ‘46’ would match and cause the surcharge
notification message to be suppressed (if surcharging were enabled). A card with the starting
number ‘581235’ would not match and therefore a surcharge message would appear. With this
technique cards from many issuers can be supported. The more digits entered the fewer the number
of different cards that will match.
If a card number matches an ISO number to be blocked, the customer will not see the surcharge
notification screen. The processor will also be notified of this in the transaction. Most processors
support this function. Before enabling this feature, check to make sure your particular processor
supports it. Otherwise, your terminal could be in violation of network rules and be sanctioned.
