Android POS System closed loop ewallet
Budget: $750 – $1,500 USD
Programming Requirement: Basic Android-based POS System
Project Overview
I need a basic Point of Sale (POS) system built for Android. The primary function of the system will be to process transactions using a closed-loop card system and QR codes. The app will not handle inventory management but will focus exclusively on credit tracking for cards and QR code-based billing. It must be simple, efficient, and secure.

Key Features
1. Billing Capabilities
2. Generate digital or printable payment receipts after each transaction.
3. Allow users to view a history of their past transactions.
Process transactions by:
Tapping a closed-loop card to deduct credits.
Scanning a QR code to retrieve and bill the pre-loaded amount displayed.
Allow manual entry of an arbitrary billing amount as an alternative.
2. Credit Tracking
Deduct credits from the tapped card after a transaction.
Add credits to a card through an admin-level feature.
3. Card and QR Code Integration
Track by card and card number only (no linking to user data).
Handle QR codes containing billing information securely and efficiently.
4. Platform and Operation
Android-only system.
Operates offline with local storage for transactions (no network or cloud integration required).
Requirements
• QR Code Integration:
Built-in QR code scanner to retrieve transaction amounts and process payments based on scanned data.
• Clean, user-friendly interface.
• Secure handling of card data, credits, and QR transactions.
• Robust error handling (e.g., insufficient credits, invalid QR codes).
Timeline and Cost
• Development Start: December 2024.
• Expected Completion: TBD (please provide your estimated timeline).
• Budget: Please provide a quote based on the features described.
