9.5.8Visa PED Mode Option

This option controls whether the terminal runs in Visa PED mode. In this mode, if prompt MAC verification fails, PIN exhaustion validation and the three button limit will be applied when prompt MAC verification fails.

PIN exhaustion validation means that the customer can only enter their PIN three times; after the third failed attempt, the terminal returns to the idle prompt.

The three button limit means that forms that do not have Prompt MACing are limited to three buttons. If the form requires more than three data inputs, such as PIN entry or cash back amount, it must have prompt MACing.
