Beijing authorities aren't messing around when it comes to stopping the theft of toilet paper. Facial recognition technology has been deployed at one of the city's busiest tourist spots to prevent what The South China Morning Post referred to as "toilet paper kleptomania." High-definition cameras installed at the city's Temple of Heaven restrooms capture facial images and then reportedly prevents any one person from taking more than 60 centimeters (or about 23 inches) of paper within a nine-minute period, according to the report and other news outlets. If the same person appears during that period, the toilet paper dispenser stops working. Presumably, this photo session takes place at the entrance to the restroom, so some degree of privacy is maintained while patrons go about their business.
