COVID-19 and Biometric Time Clocks
Biometric time clocks present similar surface contact risks as shared door handles.
Proper cleaning and hygiene significantly reduce transmission concerns.
Risk Overview
| Device Type |
Contact Risk Level |
| Fingerprint Reader |
Surface contact (similar to doorknobs) |
| Facial Recognition |
Touchless (except during enrollment) |
| HandPunch |
Hand surface contact |
Providing hand sanitizer near the clock is a practical preventive measure.
Proper Cleaning Procedures
- Do not spray ammonia-based cleaners (such as Windex) directly on sensors.
- Use rubbing alcohol or medical alcohol swabs (no stronger than 50%).
- Use a lint-free cloth — not paper towels or tissue.
- Dampen cloth lightly and wipe sensor surface gently.
Important Model-Specific Notes
- Fingerprint readers will not scan wet or soapy hands.
- Facial recognition units should be wiped only across the lens surface.
- HandPunch red lens: clean with soft cloth and water only. Alcohol may cloud the lens and require factory repair.
- HandPunch platen may be cleaned with mild solution; material is antimicrobial by design.
Routine hygiene and correct cleaning practices protect both employees and equipment.
FAQ
Can disinfectant sprays damage biometric clocks?
Yes. Direct spraying or ammonia-based cleaners can damage sensors.
Is facial recognition safer during outbreaks?
Yes. It operates touch-free once enrollment is complete.
