Looks like a fun weekend project:

This post is to shows how to exchange arbitrary data between an Android phone and an NFC reader application. To make things a bit more interesting, we'll tunnel an HTTP download over NFC. The Android app provides a URL which the terminal (we assume it's connected to the Internet) will download and send back to the app.

Specifically, this post will show how to build:

  • An Android app that uses NFC with Host Card Emulation to perform bidirectional communication with an NFC reader application.
  • A simple NFC reader application based on libnfc and libcurl.

Full sample code for this post is available at https://github.com/classycodeoss/android-nfc-http-tunnel.

    My usually nefarious imagination is failing me today. Is this to hack the NFC reader? No, it seems the reader must cooperate. So it is just a bizarre proxy?

    Inspire me...
