However, in the actual service circulation process, the existing reader-writer often relies heavily on an upper control computer (such as an upper computer) to perform data transfer and instruction issuing, and for the scenes of high-frequency transaction in a peak period of passenger flow, adaptation of a newly added ticket card medium and the like, the strongly coupled architecture mechanism often lacks independent processing capability to cause response delay and even service interruption. In addition, in order to cope with the requirements of updating operation rules or accessing new media, complex customized modification and joint debugging are often required to be carried out on an upper computer program, and system compatibility faults and single-point failure risks are easy to cause.
