TagBit 1.0

A lightweight python library for reading and writing to NFC tags via PC/SC

TagBit

TagBit is a lightweight python library for reading and writing to NFC tags through the PC/SC API.

I built this library because nfcpy lacked support for the Sony PaSoRi RC-S300. Because I built it around that device it isn't yet guaranteed to work with other readers, although since it is built around PC/SC it should have basic support for most readers.

TagBit uses pyscard to interface with the NFC reader.

Installation

You can install TagBit from PyPI using pip.

pip install tagbit

Usage

TagBit can be used to read and write NDEF messages, and to create dumps of Amiibos. Here are some examples:

Reading

from tagbit import Reader

reader = Reader()

tag = reader.get_tag()

records = tag.read()  # Returns the NDEF records from the tag.

Writing

from tagbit import Reader
import ndef  # https://pypi.org/project/ndeflib/

records = [
    ndef.TextRecord("Hello, world!", 'en'),
]

reader = Reader()

tag = reader.get_tag()

tag.write(records)  # Saves the NDEF records to the tag.

Amiibos

from tagbit import Reader

reader = Reader()

tag = reader.get_tag()

amiibo_id = tag.get_id()  # Returns the UID of the Amiibo.

amiibo_bin = tag.dump()  # Creates a dump of the Amiibo.

Plans

• Add support for MIFARE Classic 1k and other formats
• Add tools for creating Amiibos from dumps
• Test with other NFC reader models and expand compatibility
• Improve NDEF implementation if needed
