A night of partying may be all in good fun, until it's time to go home that it. All too often, late night revelers get behind the wheel after a one drink too many. Accidents caused by drunk driving is a major problem all around the world, and the city state of Singapore is no exception.

But one nightclub is taking an unconventional approach to prevent drunk driving. The solution - a 'Pee Analyser'.

Working with marketing agency DDB Group Singapore, popular nightspot Zouk came up with the charmingly named Pee Analyser, a urinal-based system that detects the amount of alcohol in a punter's pee before issuing a warning if they're over the legal limit.

And here's how it works. When a driver arrives at the club, they hand over their keys in exchange for an RFID parking card. Once activated, the card is capable of identifying a driver and recording information regarding the driver's alcohol level.

It does this by way of a urine testing device fitted in the urinal, a device that its maker says will instantly reset to accommodate consecutive readings, thereby avoiding any mix-ups with the pee of previous urinal visitors.

The urinal-based testing device is paired with an RFID reader that detects, tags and reads information from the cards, so if a patron's pee contains too much alcohol, a message will flash up on a screen directly in front saying - "Maybe you've had one too many to drive. Call a cab or use our drive home service."

Of course, there's a chance the person peeing may be too drunk to focus on the words in front of them, or simply too wasted to compute the information, so when they hand in their card at the end of the night in exchange for their keys, an RFID reader at the exit will convey the information from the tagged card to the valet, who'll once again suggest the car-owning clubber to make alternative arrangements for getting home.

The pee analyser may be the most technologically advanced approach, but some experts have called urine testing an unreliable method for determining alcohol impairment.

And although the system is only installed in male toilets, we reckon it still does some magic in curbing the numbers of drink drivers. Good work there, Zouk. Check out the below video from DDB Group Singapore to learn more about the system.
