When you see "Duplicate punch detected"

What this message means

"Duplicate punch detected. It has been X seconds since your last punch. Please wait Y more seconds." appears when you punch again within 60 seconds of your previous punch.

This safeguard prevents the same clock-in or clock-out from being recorded twice. It is not a malfunction. Just wait the number of seconds shown, and you can punch again.

How to fix it

1. 1.Wait for the number of seconds shown in "Please wait Y more seconds."
2. 2.Press the punch button once more.
3. 3.You are done when a confirmation such as "Clocked in" or "Clocked out" appears.

Tip: Even if the screen feels slow, do not tap the button repeatedly. Repeated taps keep triggering this error. Press once, then wait a few seconds.

Common causes

• Pressing the punch button twice in a row
• Pressing again because nothing seemed to happen
• Face, QR code, or IC card being read twice in an instant

If you still cannot punch

• If the same error continues after waiting more than 60 seconds, check your connection, reload the screen, and try again.
• If the punch time is wrong or was not recorded, request a correction from #ATT-001.
• If it is still not resolved, contact your attendance administrator.

Note: Canceling a clock-out

If you punch again right after clocking out (within a few tens of seconds), it is treated as canceling the clock-out (resuming work). The duplicate-punch error does not appear in that case.
