Reads and records HID Prox Card IDs for classroom attendance tracking
Raspberry Pi (I'm using the Zero W, but others should work fine) connected via USB to a 125 kHz RFID card reader that connects to a computer as a keyboard (I'm using this card reader from Amazon but others should work with some tweaking).
pip install keyboard
sudo cp attendance.service /lib/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable attendance.service
