A province in northern China developed an app to tell users whether they are within a 500-meter radius of someone in debt, state media said. It's called a "map of deadbeat debtors," the China Daily state-run newspaper reported. It hopes to get citizens to monitor the so-called debtors and report them to authorities if they seem "capable of paying their debts." It's part of China's invasive "social credit" system, designed to judge a person's trustworthiness. People have already been punished by it.
