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

For a detailed discussion of PINpad Security Best Practices, see the 
MX 900 Reference Manual.

Countertop without

Use signage 
behind the PED

Install so that customer is 
between PED and next in queue
