A bizarre video has emerged from China of a public toilet which has been fitted with facial recognition technology to cut down on toilet paper waste.<br /><br />To get paper from the public convenience in Fuzhou, Fujian Province people are now forced to stand in front of a machine on the wall which scans their faces for around three seconds before dispensing exactly 70 centimetres of toilet paper.<br /><br />Should a person require more paper, he or she would need to wait nine minutes before the machine would dispense the paper.<br /><br />So far the machine has cut paper waste by half, according to local authorities.
