About the business
I run a food packing unit with about 40 workers. People come through the staff entrance with wet or floury hands, all day.
The problem
The fingerprint reader at that entrance failed constantly. Workers pressed, then pressed again, and a queue built up at every shift change.
Fingerprint needs touch, and wet, dirty or worn fingers fail more often. That's not a fault in the reader. It's just how the method works.
What we did
We compared both honestly. Fingerprint is cheaper and proven. Palm vein needs no touch, but it costs more and has far less independent testing behind it.
So we put palm vein on that one wet-hands entrance, and nowhere else. The office doors stayed on cards. Palm users signed written consent, and anyone who declined got a card instead.
The result
The queue at that door eased. And we didn't spend on palm readers for doors that never needed them.
My lesson: pick the method for the door, not for the brochure.
If your problem is staff discomfort with cameras rather than wet hands, read why one center said no to face recognition.
