Use the following techniques to provide effective screening of PIN-Entry
Devices (PEDs) during the PIN-entry process. You can use these
methods in combination, although in some cases a single method might
sufce.
• Position the terminal on the check-in stand in such a way as to block
visual observation of the PIN-entry process. Examples include:
• Visual shields designed on the check-in stand. The shields
may be solely for shielding purposes or may be part of the
general check-in stand design.
• Position the terminal so that it is angled in such a way that PIN
spying is difcult.
• Install the PED on an adjustable stand that allows consumers to
swivel the terminal sideways and/or tilt it forward/backward to a
position that makes visual observation of the PIN-entry process
difcult.
• Position 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 measures to protect against PIN capture in four
observation corridors:
