Toilet paper thieves stopped by facial recognition

Facial recognition has been used for a wide range of hi-tech applications in China – from airport security clearance to crime prevention. Now it is being used to solve a more down-to-earth problem. On Shamian island, a popular historical tourist attraction in Guangzhou, facial recognition for toilet paper dispensing has been introduced in some cubicles, according to a report in the Guangzhou-based Information Times. Users can remove 90cm of toilet paper after their face is recognized. If the system detects the same face twice within 10 minutes, no further paper will be dispensed.
