A Valid Card Doesn’t Always Mean Someone Entered.
What if your access control system records “Access Granted” the moment a card is validated even when the person never passes through the turnstile?
That is the “Card Valid, No Passage” challenge.
Nundnet® takes a different approach.
With intelligent turnstile controller technology, the access process can move beyond simple credential validation. After a card or other credential is approved, the controller monitors the passage using infrared sensors. Sensor activity is tracked as the person moves through the lane, and the final sensor pair can be used to confirm that the person has actually completed the passage.
Only after verified movement is detected is the passage event communicated to the host access control software.
Authenticate → Detect Movement → Verify Passage → Record Entry
This approach can help deliver:
✓ More accurate access records
✓ Better occupancy information
✓ Stronger anti-tailgating protection
✓ Improved security investigations
✓ More reliable emergency roll-call data
✓ Better integration with intelligent security systems
The future of access control is not simply knowing who has permission to enter.
It is knowing who actually entered.
