Abstract: In order to solve the problems of various kinds of preferential tickets in the process of ticket electronization, and improve the efficiency of manual ticket checking, a hand-held ticket checking machine based on Android 6.0 system was developed.It adopted the built-in card reader and two-dimensional code scanning gun for data collection, and added the OCR (optical character recognition) function for the unreadable certificate. Based on the mobile 4G network or the railway GSM-R wireless network, the network transmission was implemented through the proprietary Access Point Name(APN) channel.The machine has been tested in Hainan Round Island railway. The test results show that the machine can complete a check-in operation within 2 s, which is effective and efficient, and provides an effective solution for handling all kinds of abnormal situations in the manual check-in port in the process of ticket electronization.
