The public bathroom at Beijing's Temple of Heaven Park now has a toilet paper dispenser outfitted with a camera and facial recognition technology to prevent toilet paper theft. From the New York Times:
Before entering restrooms in the park, visitors must now stare into a computer mounted on the wall for three seconds before a machine dispenses a sheet of toilet paper, precisely two feet in length. If visitors require more, they are out of luck. The machine will not dispense a second roll to the same person for nine minutes.
At the Temple of Heaven Park, one of Beijing’s busiest tourist sites, many people said on Monday they were pleased by the new machines.
“The people who steal toilet paper are greedy,” said He Zhiqiang, 19, a customer service worker from the northwestern region of Ningxia. “Toilet paper is a public resource. We need to prevent waste...”
I agree with park visitor Wang Jianquan, 63: “The sheets are too short."
