Create a card

On the machine with the card reader put a blank card on the reader and, as root, run:

# MIFARE_KEY_A=<secret1> MIFARE_KEY_B=<secret2> write_card

NFC reader: ACS/ACR122U PICC Interface opened
Waiting for card
Writing card ...
Hash: <SHA256 hash>
Wrote: <some bytes>
Read: <the same bytes>

Update hula

Copy the card hash to the "Access card" field.

Update databases

The doors will automatically download card data every 60 minutes.

For brus, see the psql log on brus.hackeriet.no -- or fix the integration.

Troubleshooting

Card Reader not working

• Check if it works with libnfc tools (nfc-list, nfc-mfclassic)
• Check that it has enough power (use a USB hub)
• On RPi make sure the firmware is current (rpi-update)
• Try reseating it, it will fail intermittently on many rapid open attempts(?)
