3D Face vs Fingerprint: Which Unlock Method Survives an Export Market
Both work in a showroom. The difference shows up in month six, when the door is dusty, the user’s hands are wet and the installer is three countries away.

Notes from people who test the lock, not the brochure.
Choosing a smart-lock brand for your market: the 2026 checklist
— Every distributor has the same story: the first container is fine, the second has a model that fails, and by the third the supplier stopped answering. These nine questions predict that outcome before money moves. ## 1–2: Who owns the brand Ask for the trademark registration, not a logo file, and ask who is […]
Why face-recognition locks fail in hot climates
— The datasheet says −20 °C to +40 °C. The afternoon surface temperature of a steel gate in Lagos or Ho Chi Minh City is 60 °C. That gap is where most field failures come from, and it is not the fingerprint sensor. ## What fails first **The lithium cell.** A 4200 mAh Li-ion pack […]
Inside the 72-hour test gate every lock must pass
— A lock is mechanical and electronic at once, and the two fail in different ways. These are the gates every unit passes before it is packed. ## Gate 1 — Incoming components Semiconductor sensors, face modules, cells, mortise bodies and cylinders are sampled before assembly: sensor response on a reference finger, cell voltage and […]
