Since the abolition of provincial border toll stations, the proportion of vehicles using ETC has gradually increased, but there are still some vehicles using CPC card. In order to reduce the work intensity of on-site personnel, improve the service quality and efficiency, and reduce the enterprise operating costs, the automatic card issuing robots are applied in more and more expressway toll stations. By summarizing the application status of existing automatic card issuing robots, comparing the advantages and disadvantages of different automatic card issuing robots, and analyzing the existing challenges of automatic card issuing robots, the optimization suggestions are proposed, which provide reference for the operation of expressway collecting toll.
