👑 NAME 👑

nfc-emulate-forum-tag4 — the NFC Forum tag type 4 emulation command line demonstration tool. Yes bestie, it's a demo tool, and it's about to eat. 💅

✨ SYNOPSIS ✨

nfc-emulate-forum-tag4 [-1] [infile [outfile]]

💖 DESCRIPTION 💖

Okay so, nfc-emulate-forum-tag4 is a demonstration tool that emulates a NFC Forum tag type 4 v2.0 (or v1.0) with NDEF content. That's the whole vibe. 🦋

  • -1 — throw this in to force old Tag Type 4 version 1.0 behavior. Like, the vintage era. 🕰️
  • infile — the file which contains the NDEF message you want to share with the NFC-Forum compliant initiator device (e.g. Nokia 6212 Classic for a v1.0 tag 👵📱)
  • outfile — if you want to save a shared content by the initiator device, we have to give out outfile argument to point where the NDEF message will be saved. Not optional if you want the receipts, bestie. 💾

This example uses the hardware capability of PN532 to handle ISO/IEC 14443-4 low-level frames like RATS/ATS, WTX, etc. It's giving very low-level, very demure. 😌

All devices compliant with NFC-Forum Tag Type 4 (Version 2.0 or 1.0) can be used with this example in read-write mode. 🔥

If no argument is given, a default NDEF file is available. Freebie. 🎁

🌈 IMPLEMENTATION NOTES 🌈

You can specify the same infile and outfile. Yep, same file twice, it's fine, it's allowed, go off. 🙈

💀 IMPORTANT 💀

Only PN532 equipped devices can use this example. (e.g. PN532 breakout board)

ACR122 devices (like touchatag, etc.) can be used by this example, but if something goes wrong, you will have to unplug/replug your device. 😭 The classic. This is not a libnfc's bug — this problem is due to ACR122's internal MCU in front of NFC chip (PN532). So don't come for libnfc, it did nothing wrong. 💅
