Are handheld barcode scanners safe?

Are handheld barcode scanners safe?

2025-06-27

I. Safety Level
Most commonly used scanners are class 2 or 2M laser devices with power ≤ 1mW, which is a low risk type.
2.Why is it safe?
Human eye protection mechanism: when the light beam accidentally shines on the eyes, people will instinctively blink (response within 0.2 seconds) to avoid prolonged exposure and reduce the risk of injury.
Design Optimisation: The beam of the 2M class device has a larger dispersion angle and more dispersed energy, which further enhances safety.
3.Precautions
Avoid intentionally looking directly into the beam for a long period of time (may slightly damage the retina).
Do not aim the beam at other people's eyes, especially children need to pay attention to supervision.
Choose the right brand and make sure the device has passed the safety certification (e.g. FDA, CE).
