As Chinese society increasingly forgoes cash in favor of mobile payments, beggars are following suit. Wang, who has begged in Shenzhen, Guangdong province for nine years, has developed a new way to beg by letting donors scan the QR code pasted on his cup. After spending 500 RMB (about $73) on a smartphone years ago, Wang now receives a daily income of 80 to 90 RMB via the phone.
