一种金融IC卡预授权方式在地铁AFC系统的应用

A Financial IC Card Pre-authorization Method in Subway AFC System

在当前地铁AFC系统中,金融IC卡过闸主要有ODA和预授权二种实现模式,预授权模式在减少单边交易量等方面更有优势。对比了ODA模式与预授权模式的优劣,在预授权模式进出站以及客服处理流程基础上,介绍了一种准实时异步请求“预授权完成”的方式,该方式优化了金融IC卡出站流程,降低了出站响应耗时,提高了通行效率。

Currently,ODA and pre-authorization of financial IC is mainly two application mode in the subway AFC system,and the pre-authorization mode has more advantages in reducing the amount of unilateral transactions.This paper compares the advantages and disadvantages of ODA mode and pre-authorization mode,on the basis of pre-authorization mode entry and exit and customer service processing flow,introduces the way of quasi-real-time asynchronous request pre-authorization completion.The financial IC card outbound process is improved,and saves outbound time and improves traffic efficiency.
