NFCPay System Architecture & Overview

NFCPay is a complete contactless payment platform designed to simplify NFC tap-to-pay, card management, peer-to-peer transfers, and secure merchant payment acceptance for businesses and individuals — accessible via a mobile app, a website, and an admin panel.

Core Platform Components

User Mobile App

A user-friendly Flutter app where users tap to pay via NFC, add money, transfer funds peer-to-peer, manage saved cards, set a default card, switch into merchant mode to receive payments, and track full transaction history.

Admin Control Panel

A powerful admin dashboard to manage users, currencies, fees & charges, deposit methods, NFC configuration, SEO, SMTP, push notifications, support tickets, and overall platform settings from one place.

Payment & NFC Engine

Handles contactless NFC tap-to-pay, manual add-card and card-scan flows, peer-to-peer transfers, and merchant-mode payment acceptance, logging every payment, transfer, and add-money event in real time.

Security & Support

Protects every transaction with email verification, two-factor authentication (2FA), and KYC verification, backed by admin role management plus user and admin support tickets, live chat, and contact messages.

Operational Workflow

01
Server Setup:Prepare the hosting environment, install the required server dependencies, and configure the database and .env file so the backend API is ready to serve the admin panel and mobile app.
02
Admin Panel Configuration:Log into the admin panel to set up currencies, fees & charges, deposit methods, NFC settings, SMTP, and other platform-wide configuration before onboarding users.
03
Flutter Environment Setup:Set up the Flutter development environment, connect it to the configured backend, and update app-level settings such as the API URL, app name, package ID, and keys.
04
App Installation & Testing:Build the app, install it on Android/iOS test devices, and verify that NFC tap-to-pay, wallet, transfers, and merchant mode work correctly end-to-end.
05
Deployment:Generate signed release builds and publish the user app to the Play Store/App Store, then deploy the website and admin panel to production.
