Non-Contact Alcohol Detectors

Non-contact detectors sense alcohol in exhaled breath without a mouthpiece — the person breathes toward the device from a short distance rather than blowing into it. That removes the single biggest bottleneck in high-volume screening: no disposable mouthpieces to hand out, unwrap and dispose of between every person.

Because there's nothing to sanitize or replace between users, these devices are built for speed — screening a queue of people in minutes rather than one at a time with a mouthpiece swap in between.
