A park in Beijing, China has a trial to try and save toilet paper and thieves from stealing it. Park officials have six facial recognition scanners at the city's Temple of Heaven Park. The machines will someone's face before providing him or her with 60 cm of toilet paper. That same person will then have to for nine minutes if they extra paper. A park spokesman said there was a problem of visitors to the toilets taking too much toilet paper. He said some people and filled their bags with it. The park had up posters and messages over loudspeakers asking visitors to less toilet paper.

The new facial recognition scanners have a surprise. They have a tourist attraction. Visitors are now to look at and try out the machines. Videos of people pulling strips of toilet paper from the machines have viral on social media sites. Staff are available to people with problems using the machines or for people who urgently more toilet paper. The scanners seem to popular. A user on the Chinese social media site Weibo commented: "This is a really good idea. I that it be rolled out in toilets nationwide." The trial appears to successful so far. The daily amount of toilet paper used in the park's toilets has down by 20 per cent.
