PN5180-tagomatic

USB based RFID reader with Python interface

Overview

PN5180-tagomatic is a USB-based RFID reader that provides a Python interface for reading NFC/RFID tags using the PN5180 NFC Frontend module and a Raspberry Pi Pico (Zero).

Features

• Python library for easy integration.
• Uses USB serial communication to the reader.
• Cross-platform support (Linux, Windows, macOS).
• Finds and selects single ISO/IEC 14443 cards.
• Uses NFC FORUM commands to read/write 14443-A cards' memories.
• Can authenticate against Mifare classic cards to read their memories.
• Finds ISO/IEC 15693 cards, uses 15693-3 commands to read/write their memories.

Multiple cards in the RFID field is currently not really supported, the hardware and arduino sketch supports all commands for it.

Installation

Python Package

Install from PyPI:

pip install pn5180-tagomatic

Install from source:

git clone https://github.com/bofh69/PN5180-tagomatic.git
cd PN5180-tagomatic
pip install -e .

Firmware

See sketch/README.md for instructions on building and uploading the Raspberry Pi Pico firmware.

Usage

from pn5180_tagomatic import PN5180


# Create reader instance and use it
with PN5180("/dev/ttyACM0") as reader:
    versions = reader.ll.read_eeprom(0x10, 6)
    with reader.start_session(0x00, 0x80) as session:
        card = session.connect_one_iso14443a()
        print(f"Reading from card {card.uid.hex(':')}")
        if len(card.uid) == 4:
            memory = card.read_mifare_memory()
        else:
            memory = card.read_memory()
