We created a smart device, depending on the blood alcohol content from a breath sample, the device sends a signal to release or keep your car keys.

What did we do?

We took a certificated Breathalyzer, and then we programmed a unique microprocessor and connect it to the Breathalyzer, combined with the alcohol lecture on the breath, sends a micro pulse to a mechanism that releases the car keys. We created a light code to measure the results; the green light turns on when the percentage of alcohol is below the limit, the red light turns on when the alcohol concentration is above the limit.

We created a special container with specific dimensions, designed to hold the mechanism and allow total visibility of the driver’s keys.

In the main bars and restaurants of Mexico City we equipped the valet parking with the device, so when the driver leaves the place, has to blow into the device to get the result: if the alcohol rate was below the limit, the device released the keys along with a discount coupon for your next visit, if your alcohol rate was above the limit, the device remains closed with the car keys inside and Corona will provide a Corona driver to take you home safely.

The project is currently in beta stage and taking 8 of the main bars and restaurant in Mexico City as sample; the results have been favorable:

• 73% of Corona Drivers have been used.

• In business terms: 66% of coupons have been redeemed.

In the next stage, the action will be in the major cities in Mexico and other countries where Cerveza Corona has presence.

Although we can’t prove it, we are sure that those nights lives were saved.
