DESCRIPTION:
This function is used to block surcharging and to disable the dis-
play 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 man-
agement 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 num-
ber. 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 cus-
tomer will not see the surcharge notification screen. The proces-
sor 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 termi-
nal could be in violation of network rules and be sanctioned.
