Meet the SCRAM: a remote alcohol breath testing device with automated facial recognition and GPS location tracking. It can serve as a wireless alcohol testing option for law enforcement officers. The device relies on automated facial recognition to make sure the correct individual is taking the test. It can store up to 48k test results. The device also captures location information for all missed and completed tests.
The SCRAM is not for everyone, but if you are dealing with hardcore DUI alcohol offenders, it could prove useful. 3M will be marketing the device for now.
