Method for improving traffic one-card transaction performance, computer device and computer readable storage medium

Abstract

The invention provides a method for improving traffic one-card transaction performance, a computer device and a computer readable storage medium. The method comprises the steps of obtaining a first balance value of a first payment application and storing the first balance value into a first byte type array cache unit; querying the first balance value bit by bit according to a preset data mapping table to obtain list data corresponding to each number in the first balance value; and accumulating and adding the list data corresponding to each number to obtain a second balance value of the secondpayment application, and storing the second balance value in a second byte type array cache unit. The computer device is provided with a processor, and the method for improving the traffic one-card transaction performance can be achieved when the processor executes a program. The computer readable storage medium is equipped with a computer program and is used for achieving the method for improvingthe traffic one-card transaction performance. By applying the method, the conversion speed and efficiency can be improved, so that the card swiping transaction performance of the whole traffic all-purpose card can be improved.

Description

technical field [0001] The present invention relates to the technical field of smart cards, in particular to a method for improving the transaction performance of a transportation card, and also to a computer device applying the method and a computer-readable storage medium applying the method. Background technique [0002] In the field of transportation, led by the Ministry of Communications, all cities across the country realize the interconnection of the transportation card, which is an important livelihood project for deepening the structural reform of the supply side of transportation services, improving the level of transportation services, and enhancing the people's sense of travel. [0003] The java card-based traffic one-card interconnection Applet application is developed in the java language, because the java language development for smart cards does not support the int type, and data conversion using the java language development can only be done using byte, short...

AI Technical Summary

Problems solved by technology

The amount of the electronic cash application is represented by six-byte decimal data, and the amount of the electronic wallet application is represented by 4-byte hexadecimal data. Therefore, there will be limitations in using the multiplication and division rules and shifting rules in data conversion in applet development. Sex, and the conversion efficiency is extremely low, which will slow down the transaction speed and reduce the cardholder's card swiping experience
