Python NFC card reader for the Raspberry Pi, forked from https://github.com/mxgxw/MFRC522-python.
Sends check-in and check-out requests to the backend with http://docs.python-requests.org/en/master/.
This code requires you to have SPI-Py installed from the following repository: https://github.com/lthiery/SPI-Py
sudo apt-get install python-dev
git clone https://github.com/lthiery/SPI-Py.git
cd SPI-Py
sudo python setup.py install
You may also need to add/uncomment device_tree_param=spi=on to /boot/config.txt.
You can use this for reference.

The following environment variables need to be set, for example exported from a script in /etc/profile.d/rc-check-in-env.sh.
#!/bin/bash
export RC_CHECK_IN_SERVER='http://foo.bar/'
export RC_CHECK_IN_USERNAME=foo
export RC_CHECK_IN_PASSWORD=bar
The card reader can be started by running Read.py. It can also be started automatically with the rc-check-in-card-reader.service service file.
git clone https://github.com/RefugeesCodeAT/rc-check-in-card-reader.git

sudo cp rc-check-in-card-reader.service /etc/systemd/system/
sudo systemctl enable rc-check-in-card-reader.service
sudo systemctl start rc-check-in-card-reader.service
