Earlier this year, I blogged about China's Social Credit System. Because of the system, China prevented millions of its citizens from traveling via train or airplane because of their poor social credit (see Guardian link). Social credit offenses include not paying taxes or fines, using drugs, smoking on a train, or not walking a dog on a leash.
If being denied travel rights wasn't sufficient to change a person's behavior, another application in China will show any people within 500 meters that are in debt (see ToshiTimes link). As if being flagged a debtor wasn't scary enough. The application allegedly will show you personal details such as names, national ID numbers, and details of the debt. If it does, that probably increases the chances that debtors identities may be stolen and their situations worsened.
