PIN Protection Measures
The following techniques can be employed to provide for effective screening of
the PIN-entry keypad during the PIN-entry process. These methods would
typically be used in combination, though in some cases a method might be used
singly.
■
Positioning of terminal on the check-stand in such a way as to make visual
observation of the PIN-entry process infeasible. Examples include:
– Visual shields designed into the check-stand. The shields may be
solely for shielding purposes, or may be part of the general check-
stand design.
– Position the PIN Entry Device (PED) so that it is angled in such a way
that PIN spying is difficult.
■
Installing PED on an adjustable stand that allows consumers to swivel the
terminal sideways and/or tilt it forwards/backwards to a position that
makes visual observation of the PIN-entry process difficult.
■
Positioning of in-store security cameras so that the PIN-entry keypad is
not visible.
The following table describes the two preferred mounting methods and the
recommended measure to protect from PIN capture in four observation
corridors:
VeriFone also recommends instruction of the cardholder regarding safe
PIN-entry. This can be done with a combination of:
■
Signage on the PED
■
Prompts on the display, possibly with a “click-through” screen
■
Literature at the point of sale
■
A logo for safe PIN-entry process
