ATM + 购物商城程序
生活随笔
收集整理的這篇文章主要介紹了
ATM + 购物商城程序
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
模擬實現(xiàn)一個ATM + 購物商城程序
額度 15000或自定義
實現(xiàn)購物商城，買東西加入 購物車，調(diào)用信用卡接口結(jié)賬
可以提現(xiàn)，手續(xù)費5%
每月22號出賬單，每月10號為還款日，過期未還，按欠款總額 萬分之5 每日計息
支持多賬戶登錄
支持賬戶間轉(zhuǎn)賬
記錄每月日常消費流水
提供還款接口
ATM記錄操作日志?
提供管理接口，包括添加賬戶、用戶額度，凍結(jié)賬戶等。。。
