All code is open source and hosted on GitHub.
JZoo Customer Loyalty Program (Myanmar)
这是通过为商店提供一个简单的Android平板电脑来实现的,员工可以用它来输入销售数据, 用户可以通过扫描二维码来收集积分. 这些积分之后可以兑换成奖励.
在这个过程中,我们不得不处理许多预料到的和非常意想不到的问题,比如3G/4G网络连接非常糟糕,导致设备经常离线, shop staff not charging tablets, 电信公司无法跟踪和报告SIM卡的数据使用情况,人们试图将平板电脑作为个人使用的热点. 这就需要我们建立额外的监控工具,并加强对店铺员工的培训.
该系统被部署到仰光的120家商店,最终被关闭.
