ZKTeco Fingerprint Mini Lever Lock ML300

The ZKTeco ML300 is a compact fingerprint lever lock with Bluetooth 5.0 communication. It supports fingerprint, smartphone and passcode entry, providing a biometric option within the mini lever-lock format. An American-standard single latch is listed, with a German-standard mortise offered as an option; the ordered mechanical version needs to match the door rather than being inferred from the model photograph.

A capacitive fingerprint sensor handles biometric input, and the manufacturer lists capacities of 100 fingerprints and 100 passcodes. Local Bluetooth operation and remote access are different arrangements: remote access requires a Bluetooth gateway. This distinction matters when choosing between managing a lock nearby and controlling it from another location. Gateway compatibility and the intended mobile workflow should form part of the system specification, while the lock's own credential methods remain the basis for everyday entry.

The standard door-thickness range is 30 to 60 mm. For the single-latch version, the backset is adjustable to 60 or 70 mm; that adjustment should not be assumed to apply to the optional mortise. The enclosure combines a zinc-alloy lever and front panel with an ABS rear shell. Four AA alkaline batteries provide normal power and are not included, while a Micro-USB port supports backup power. Select the ML300 when fingerprint entry, a compact lever design and the documented mechanical arrangement fit the door and access-management plan.
