Duplicate Punch
The function "Duplicate punch " serves to avoid accidental double punching with the
same card within a short interval, i.e. unintentionally inserting the card a second time.
If this feature is enabled, the interval after which the time recorder will accept the
next punch must be programmed. The interval can be anywhere from one to 30
minutes.
When a time card is inserted a second time within the duplicate punch prevention
window, the time recorder rejects the card and displays the following rejection
reason:
"DUPLICATE PUNCH"
