Py_Library_NFC

A library can be used to interact with nfc cards and readers

Standalone code takes care of converting the data (strings, integers, bytes, ndef messages) to a bytearray that can be written to the card and reader. Pyscard is used to actually transfer / read the bytes to / from the card. Ndeflib is used to format according to the NDEF message standards.

Roadmap

Getting Started

pyscard

for windows:

pip install pyscard

for ubuntu:

sudo apt install swig
sudo apt install -y python3-pyscard
sudo apt install pcscd # needed to scan for readers on ubuntu

# if you get errors (ARC nfc reader has this with ubuntu)
sudo vim /etc/modprobe.d/blacklist-libnfc.conf
# Add this line: blacklist pn533_usb
# Reboot

ndef library

pip install ndeflib

Development

NFC

connecting with Pyscard

Should be usable with python version 3.3 or higher, but Tested on version 3.6.8.

encoding with ndeflib

encoding and decoding messages from NDEF format (nfc data exchange format)

https://pypi.org/project/ndeflib/ https://ndeflib.readthedocs.io/en/latest/ndef.html

Running the tests

After cloning the repo and downloading the dependencies, run the following script:

python3 test_class_nfc.py

To test completely it expects a valid ARC nfc reader and a presented nfc card

Break down into end to end tests

And coding style tests
