There are plenty of different ways to make an alcohol test on a person, but the one provided by TruTouch is certainly incomparable.
Instead of using a normal breathalyzer like the cops do, or doing a blood test like it happens on hospitals, the product developed by TruTouch is able to check the alcohol percentage on your system by analyzing your skin.
The new technology relies on near infrared reflectance spectroscopy to noninvasively measure alcohol through the subject’s skin.
Just place the arm of the “suspect” on the device and 30 seconds later you have a result. I think it is the most easy-to-use alcohol testing system, don’t you?
