A temple in Beijing has installed a face recognition device to ensure that no one takes more than their fair share of toilet paper.People using the toilet in Tiantan Park in Beijing – one of the city's major tourist sites – will only receive a 60 centimetre serving of paper after they have conducted a facial scan.After meting out the loo roll, the software will deny the same person paper within nine minutes of their first scan, reports said.”Some people still lack paper use manners,” said a report by China Radio International (CRI).CRI cited a toilet attendant saying: “Some people take much more paper than needed and sometimes even take a whole roll away with them”.
