## Overview

POS Kasir Pro is an Android-hosted point-of-sale system whose web interface is served over the local network for use on the device or by other devices on the same network. The documented workflow is to sign in as owner or operator, configure the shop and products, then use sales and related operational features; finance and reporting provide supporting workflows. The tree exposes the web app modules and two database files, but no source excerpts show their runtime wiring, Android server implementation, or online-shop implementation, so those connections are not inferred.

Main entry points: [`assets/www/index.html`](https://github.com/novri3h/android-poskasir/blob/master/assets/www/index.html) (POS web app), [`assets/www/apps/login/login.js`](https://github.com/novri3h/android-poskasir/blob/master/assets/www/apps/login/login.js) (Sign in), [`assets/www/apps/operator/operator.js`](https://github.com/novri3h/android-poskasir/blob/master/assets/www/apps/operator/operator.js) (Operator access), [`assets/www/apps/product/product.js`](https://github.com/novri3h/android-poskasir/blob/master/assets/www/apps/product/product.js) (Products and prices)
