📡 Near-Field-Communication-Project

Welcome to Near-Field-Communication-Project, a dual-platform solution for interacting with NFC (Near Field Communication) tags and devices.
This project combines the power of Web NFC and a native Android NFC reader app to offer seamless tag detection, reading, and writing capabilities.

🧠 About the Project

This repository demonstrates two approaches to NFC interaction:

• Web NFC → Uses the experimental Web NFC API to read/write NFC tags via supported browsers.
• Android NFC App → A Kotlin-based mobile app built with Android Studio that supports reading and writing NDEF messages from physical NFC tags.

🛠️ Technology Stack

Platform	Technologies	Notes
Web NFC App	HTML, CSS, JavaScript, Node.js, Express, Vercel	Built for browsers supporting the experimental Web NFC API. Uses Node.js + Express for backend and deployed via Vercel.
Android NFC App	Kotlin, Android SDK	Native mobile app built with Android Studio. Supports reading/writing NDEF messages from physical NFC tags. Different stack from Web NFC since it leverages Android’s NFC hardware APIs.

📖 Usage Guide

Follow these steps to get started with the project:

🔹 Web NFC App

1. Open Web NFC App in Chrome for Android (Web NFC is not supported on desktop browsers).
2. Tap your NFC tag on the back of your Android device.
3. The app will detect and display tag information.
4. Writing NDEF messages is currently in progress but reading works seamlessly.

🔹 Android NFC App

1. Download the APK file.
2. Install it on your NFC-enabled Android device.
3. Launch the app and bring an NFC tag close to your device.
4. The app will read the tag and display its contents.
5. Writing NDEF messages is supported for compatible tags.
