Zhang Guozhong, a bus driver working in the Nan'an region of Chongqing, has reached out to passengers who don't carry small change by essentially giving out a series of tiny loans, which passengers then repay electronically.
Zhang's daily route goes from Panlong Mountain to Shuangfeng Mountain Road, the latter of which is visited by many tourists on weekends. Most tourists don't have bus cards as locals do, so it can be inconvenient for them to take the bus if they aren't carrying small change.
Inspired by several passengers who inquired about e-payments, Zhang purchased a bus card for those without one. Passengers who use Zhang's card repay him after their rides via WeChat, a popular payment service in China.
Since December 2016, almost 100 passengers have utilized Zhang's shared bus card. He feels quite gratified that not a single person has failed to repay him in full after using the card.
