designer's own words:
Driving under the influence is a threat to public safety and needs to be properly discouraged. Common breathalyzers are prone to wide error margins that end up with more dispute than necessary.
Saliva alcohol tests are easier to administrator and more objective. The “O-Key” features a saliva testing chip, detection device, O-Key smart phone kit, and O-Key portable detection device kit. The smart phone app analyzes the blood alcohol level and can either directly call for a cab or someone for pickup, as well as saving the current location.
O-Key is a combination of “OK” and “key”.
