Abstract: Firstly, this paper introduces the internet ticketing system, QR code type, transaction process and other related information of QR code ticket; secondly, it introduces three existing QR code ticket interconnection technology schemes, and analyzes their advantages and disadvantages; finally, combined with the construction and operation of Suzhou Metro QR code ticket, the interconnection scheme evaluation index system is constructed considering the transformation cost, operation benefit, passenger experience, sustainability and other factors. Based on the analytic hierarchy process (AHP), the evaluation of each implementation scheme is carried out, and the optimal technical scheme in line with the situation of Suzhou is finally determined. This paper discusses the interconnection scheme of QR code ticket, which provides a reference for the practice of inter-city rail transit ticketing system interconnection, and has certain industry guiding significance.
