In China, beggars now accept donations via mobile payments and QR codes

In China, beggars now accept donations via mobile payments and QR codes, where beggars ask passers-by to transfer money to them using Alipay and WeChat Wallet via smartphones. Where beggars in China have accepted electronic e-payments through mobile payments by scanning QR codes on smartphones.
An example is Jinan City, a city in east China's Shandong Province, where beggars who travel to popular tourist destinations such as Wang Fu have turned to pay by mobile phone to increase their chances of receiving donations from the general public.
The beggars place a printed copy of the QR code on their begging dishes. QR codes enable anyone with a mobile payment application such as Alipay to Alibaba or Tencent's WeChat to scan the code and send a certain amount to the mobile phone's mobile account.

This idea seems to work by encouraging people to scan QR code. It is likely that no amount is deducted from the sender, that is, pedestrians are encouraged to support beggars because they do not need to pay any money. All they have to do is clear the QR code, and the payee will be paid for each survey they can get from the app's profits.
