RC522-auth

Authentication of UID from cards with CSV provided file with data. The idea behind using the CSV type of data is that the file is reusable and compatible with other services and platforms.

CSV file

The authorized.csv file format is UID;Name;Authorization which is basically the UID of the card, Name of the user and the Authorization status (true/false).

LED light status

The LED light connected on GPIO 18 is used to determine the status whether the card is authorized or not.

Long or 3 seconds light

Means that the card is authorized (true)

Blinking light

Means that the card is unauthorized (false)
