D4 is a compact time and attendance terminal designed to take the complexity out of small and medium-sized businesses (SMBs) workforce management.
D4 offers flexible authentication options, such as fingerprint authentication and RFID card verification entry to suit different workplace preferences. The terminal adopts the ZK optical fingerprint algorithm, 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.
