We need to build internal Android app (just an APK without publishing to Google play).
The basic idea of the App:
It has 3 screens.
1. Idle screen.
2. Approval screen.
3. Decline screen.
On the idle screen, the app needs to listen to the NFC reader until it get an input. Once it receive an input, it need to send it using Restful API to our server. Our server returns True or false.
If you get the true response, you need to show the approval screen, otherwise show the decline screen. The screens will apear for 2 seconds and then it will return to the idle screen.
There some more minor specifications, I'll be sending those later.
I would prefer for someone to do it using Kotlin, but Java is also alright.
