[Multiple Regions Warn Against the 'Trial Card' Scam Involving Virtual Currency, Disguised as 'Free Benefits' to Funnel Traffic for Telecom Fraud] Shanghai, Yunnan, Gansu, Hainan, and other regions have issued warnings about the 'trial card' scam involving virtual currency. Some criminals are using the guise of 'free benefits' from well-known supermarkets to funnel traffic for telecom network fraud. According to the police, suspects responsible for traffic funneling use overseas communication software to connect with the fraud syndicate leaders. After distributing each 'trial card,' the syndicate takes individual photos, recording key information such as community addresses, house numbers, and fake promotional materials hung on door handles. This information is uploaded to the syndicate leaders, who periodically settle payments with virtual currency, making it highly concealed. The police remind the public not to participate in such 'ground promotion part-time jobs' out of greed for small benefits, as this could make them accomplices to fraudsters, leading to corresponding legal consequences.
