ESCRIPTION:
This function is used to block sur-
charging and to disable the display
of surcharge messages for transac-
tions 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 ter-
minal using Triton Connect management software.
From 1 to 9 digits may be used. The terminal will compare the card num-
ber 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 mes-
sage 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
