+
+## Architecture Overview
+
+**MOBPOS** is a mobile Point-of-Sale system for Myanmar, targeting Sunmi hardware devices (card readers, PIN pads, thermal printers). It processes EMV card transactions (sale, void, refund, settlement) and QR payments (MMQR, Wave Pay).
+
+### Single-Activity Compose App
+
+`MainActivity` hosts the entire app. Navigation is handled by Compose Navigation (`AppNavGraph.kt`) with typed routes defined in a sealed `Routes` object.
+
+### MVVM with Shared State
+
+- Each screen has a dedicated `ViewModel` (Hilt-injected)
+- `SharedViewModel` in `viewmodel/` is the central state holder for cross-screen transaction data (card info, amount, transaction type, approval codes)
+- Hardware interaction is abstracted into `CardReaderViewModel` and `EmvTransactionProcessViewModel`
+- State is a mix of `LiveData` (older screens) and `StateFlow` (newer screens like card reading)
+
+### Screen Structure Pattern
+
+Every feature follows: `ui/<feature>/` containing:
+- `*Screen.kt` — Composable UI
+- `*ViewModel.kt` — business logic and state
+
+### Key Transaction Flow
+
+Dashboard → InputAmount → CardWaiting → ProcessingCard → SendingToHost → TransactionResult → PrintReceipt
+
+### Local Modules
+
+The app depends on several local library modules (in `settings.gradle.kts`):
+- `:baselib` — Room DB, Retrofit, Hilt base setup
+- `:paylibs` / `:paysdk-lib` — Payment SDK wrappers
+- `:ecr` / `:ecr-service-lib` — Electronic Cash Register integration
+- `:mpulib` / `:mpu-lib` — Mini POS Unit hardware
+- `:sunmiui-lib` — Sunmi device UI components
+- `:qrgen-lib` — QR code generation
+
+### Key Dependencies
+
+- **UI:** Jetpack Compose + Material 3, Compose Navigation
+- **DI:** Hilt 2.59.2 with KSP
+- **Async:** RxJava 3 + RxAndroid (primary async pattern)
+- **Network:** Retrofit 3 + OkHttp 4 + GSON
+- **DB:** Room 2.4.3 with RxJava 3 support
+- **Hardware:** Sunmi SDK (card reader, PIN pad, printer APIs)
+
+### Package Layout
+
+```

+```
+
+## Hardware Integration Notes
+
+Sunmi device permissions are declared in `AndroidManifest.xml` (LED, MSR, ICC, PINPAD, PRINTER). When modifying card reading or PIN entry flows, be aware that `CardReaderViewModel` and the Sunmi ECR service handle hardware callbacks via RxJava subjects. Hardware callbacks arrive on background threads — always observe on the main thread before updating UI state.
