enabling fast fingerprint authentication less than 1.5 seconds.
What makes D4 stands out is that the terminal can be Wi-Fi networked via Bluetooth and integrate with ZKBio Zlink. This lets users manage employees and equipment, set attendance rules and check real-time attendance reports on their desktop or mobile device.
