将我的 android 应用程序与现有的 POS（销售点）系统集成

Question

Is it possible to integrate a third party app with the already available Point of Sale Systems present in retails/restaurants?

Do they expose their APIs or any such thing where I will be able to integrate my system with them. Any help would be appreciated.

Answer 1

No doubt, we can develop applications for them using Android. But, basically all the restaurants, retails don't use the same Software, that depends on them, which resource they are using. And we can't say whether they are exposing their API to develop the Android application or not. To make android application for those type of applications we need to talk with the application provider or we need to design our own API.
