The Challenge
Traditional POS hardware is expensive and inaccessible for small businesses in remote areas - merchants who can't afford dedicated terminals lose customers to competitors who accept digital payments, directly impacting revenue.
Non-technical merchants needed a payment solution they could operate confidently. Existing mobile payment apps assumed technical literacy, creating friction that led to abandonment and support overhead.
Without real-time visibility into transaction data, business owners had no way to track daily revenue, identify peak hours, or make informed operational decisions - running their business on gut feel rather than data.
What We Built
Built a Flutter mobile app that transforms any smartphone into a POS terminal - supporting contactless card payments, QR code scanning, tap-and-pay via NFC, and shareable payment links for remote transactions.
Designed the interface specifically for non-technical merchants with large touch targets, minimal steps to complete a transaction, and clear visual confirmation of payment status - reducing training time to under 10 minutes.
Created a real-time dashboard with customizable date filters, transaction history, and revenue summaries so business owners can track performance at a glance from their phone.
Built a responsive Next.js admin panel and Node.js/PostgreSQL backend for platform operations, merchant onboarding, and transaction monitoring.
Related Work
Modern smartphones have NFC chips that can read contactless cards and mobile wallets. The app uses the phone's built-in NFC reader to process tap-and-pay transactions, while QR code and payment link options work on any device with a camera or internet connection. This eliminates the need for separate card readers or POS terminals.
