To combat the rampant toilet paper theft in public toilets, local authorities in Beijing, China, have begun installing high-tech facial scanners that prevent users from taking any more toilet paper if they show up again within a certain period of time.
The public toilets at the Temple of Heaven, one of the most popular tourist attraction in the Chinese capital, used to be a hotbed of toilet paper theft. Sick of wasting huge amount of money on thousands of rolls of paper every month, local authorities recently replaced the old dispensers with high-tech ones with incorporated facial scanning technology. Now, to receive a 60-cm-long sheet of toilet paper, users must stand in front of the machine to have their face scanned and stored in a temporary data base. If they return in less than nine minutes from their previous visit, the machine will remember them and will not dispense anymore toilet paper.
