Why workers can't beat it
Face liveness blocks photo replay — a printed picture or phone screen will not pass. Multi-face detection rejects buddy-punching, so two friends cannot clock in for one shift. The kiosk learns drift over weeks, so masks, glasses, and haircuts still match.
6 reasons fingerprint machines fail in real factories
Wet hands fail
Kitchens, F&B lines, washing bays — moisture defeats capacitive sensors and queues stack up at clock-in.
Damaged fingers
Construction, logistics and manufacturing wear down ridges. False rejects punish your most senior staff.
Buddy-punching with copies
Silicone moulds and finger photos are sold for under Rp 50 ribu. Any payroll team has heard the story.
Heat affects sensors
Sensors drift in 35°C+ rooms and after long sun exposure. Re-enrollment days kill productivity.
Multi-site needs many machines
Each site = one device, one cable, one technician. A tablet ships in a box and a manager unpacks it.
No offline log when device dies
Old fingerprint boxes lose data on power cuts. Presenly keeps signed offline records and syncs later.

We ship a tablet, you mount it, your team clocks in by face. If face does not work for someone, fall back to PIN — no machine swap.
