This paper focuses on the difficulties and pain points in Chengdu Metro ticket management system. Through the application of information technology, including the Internet+, the original cash income audit is becoming paperless, and mobile payment is provided in the station ticket purchase/recharge. This solves the problem wherein the work of the ticket operation is large and repetitive, the efficiency of the manual operation is low and error-prone, and the number of professionals increases with the scale of the metro network. In fact, ticket management has become automated and networked. The results of quality improvement, efficiency improvement, and cost reduction are remarkable. At the same time, related functions are based on the transformation of the operated lines, which can provide reference for other cities to change their existing ticket management systems.
