NFC Wi-Fi Transfer 8882

Project Type: Independent Utility App / Community Project Stage: v2.0 Signed Release / Open Source on GitHub Looking for: Users, Testers & Developer Collaboration

Overview

Tap an NFC tag, pick your files, tap again — they fly from your Android phone to your Windows PC over Wi-Fi. No cables, no pairing, no cloud, no size limits, byte-exact quality. NFC Wi-Fi Transfer 8882 solves a real daily friction point between mobile and desktop, and since v2.0 the full system is open source.

What I Built

•  Android app:  Kotlin + Jetpack Compose

•  Windows receiver:  Python (tkinter), shipped as a single portable .exe — no install needed

Core features (v2.0):

•  NFC-triggered transfers — two taps and it's done

•  Up to 3 parallel upload streams over keep-alive connections: multi-GB batches move at full Wi-Fi speed

•  Write your NFC tag from inside the app — no third-party NFC tools needed

•  NFC listens only while the app is open, never in the background

•  Failed batch? Tap again — it resumes with only the missing files

•  Receiver lives in the system tray, can auto-start with Windows, and shows the IP to write on your tag

Current Status

•  v2.0 released with a signed APK

•  Full source code public on GitHub

•  Everything you need is three things: the receiver .exe, the .apk, and any NTAG sticker
