Initial Prototype
This will be a device with a display, connected to Wi-Fi, a basic Camera, a button to capture image. Once the button is pressed, image will be captured, sent to server. On the server it will be processed. And a number is generated from it. This entire thing will be happening in one API call. In the result of the API call, we will get the processed number which will be displayed on the screen. Once this is done, we just have to package all these hardware in a nice enclosure and make it look like a magic box. Only a button (Move this button to the display), camera and display will be visible.
