BACtrack appeared in an article and video by Phone Arena recently, discussing the utility of a personal breathalyzer.
"Ever wonder if you have had maybe one too many drinks after a night out with friends?" the article begins. "BACtrack has some accessories that can take a sample of your blood alcohol content (BAC) without condemning you to a legal sobriety check... BACtrack offers the ability to track your liquid diet."
He gets the products confused a little, but it's a good example of the technology at work.
"This can be a handy tool for those that have court ordered breathalyzer ignitions in their vehicles, avoiding a vehicle shut-down, and giving them the chance to make the right decision before getting behind the wheel."
