Clocking system for companies using a Raspberry Pi and a RFID-RC522 Module.
The application is in a very early phase, just for testing RFID tags. The next step is to develop a web service for data synchronization and on which to run queries.
In this early version, you need a .csv file with the employes data with this structure:
id_number,Name Surname
main.py: Run the Clock In - Clock Out System.write_new_dni.py: Use for write a new ID in a RFID tag.
- Install mfrc522 library with
sudo pip install mfrc522(or usingpip3) - Active SPI Interface in
sudo raspi-config - RPi library is included with Raspberry OS. Just update (you know,
sudo apt update->sudo apt upgrade) - Run scripts using python 3.x
This is the pin configuration for RFID-RC522 Module:
| RC522 Pin | RaspPi Pin |
|---|---|
| 3.3V | Pin 1 |
| RST | Pin 22 |
| GND | Pin 6 |
| MISO | Pin 21 |
| MOSI | Pin 19 |
| SCK | Pin 23 |
| SDA | Pin 24 |
