在线方式:售饭时,所有的售饭操作数据通过网络在计算机上实时处理。自助餐机只起到输入消费金额和显示卡余额的作用。它不需要存储任何售饭系统数据。它只是计算机的远程显示。所有餐点销售业务的经理是远程计算机,餐卡的功能是帮助识别持卡人。
线下情况比较复杂。卖饭前,必须通过电脑将所谓的挂失“黑名单”下载到所有的售饭机上进行保存。售饭结束后,必须通过软件将数据上传到电脑上进行对账汇总。如果自助餐厅的任何一台自动售餐机出现故障,整个账户将无法平衡和准确统计。餐饮卡有两个用途:识别和存储余额。
“在线与离线”是一个古老的话题。卖家有自己的意见,但买家有一个判断标准:谁的系统稳定,谁的系统好用。稳定性水平取决于: 产品的复杂性。
众所周知,越简单的东西越稳定,在这方面实时系统可能比离线系统要好。离线系统将持卡人的余额或消费记录存储在微机、自动售卖机、餐饮卡中。 如果一个地方出现故障,整套账户都会丢失。实时系统只有一套带微电脑的账户,隐患系数3比1,利弊不言而喻。这其实是导致很多售米机经销商售后服务极其繁重的根本原因!
