The main objective of this project is to build an Android-based Point-of-Sale (POS) app tailored for charitable organizations and nonprofits. The app will utilize Stripe’s Tap to Pay feature to streamline donations, allowing staff members to easily process payments in person. The app will focus on user-friendly features such as donor email collection, campaign selection, and historical payment tracking, enabling seamless donation management.

Tasks and Activities

• Learn and integrate Stripe’s Tap to Pay functionality on Android.
• Implement Firebase authentication for secure staff login using email/password and Google authentication.
• Develop a user interface that includes login, settings, payment processing, and transaction history pages.
• Handle backend communication to create and manage payment intents using existing APIs.
• Build and test functionalities incrementally to ensure a robust and reliable application.

Deliverables

• A functional Android POS app, meeting all specified milestones:

1. Project setup: A Git repository with a basic app structure that runs on an Android device.
2. Login and settings: Firebase-based authentication and basic user settings functionality.
3. Reader connection: Stripe reader integration for Tap to Pay.
4. Payment processing: A form and interface for entering donation details and processing payments.
5. Success page: Confirmation details for successful transactions.
6. Transaction history: A list of completed transactions.
