*Pi RFID Reader

15 Jan

In efforts to come up with a really simple RFID reader I expanded my project to include:

– A LCD screen
– WiFi operation.
– Programmable (writable) “Master Cards”.

Basic thought process.

– Keep minimal python script.
– Program a “master card(s)” using their ID. One card will be a “Add Card” and “Delete Card”. If the ID matches the one in the Python script then allow it to write (or delete) data to a MySQL table “registeredCards”.
– PHP script will lookup “registeredCards” then query the “cardActivity” table.

sudo su –

cp /usr/share/zoneinfo/America/Edmonton /etc/localtime

mydb = mysql.connector.connect(

mycursor = mydb.cursor()
sql = “INSERT INTO activity (name, number) VALUES (%s, %s)”

lcd = RPi_I2C_LCD.LCD()
lcd.set_backlight(True)
reader = SimpleMFRC522.SimpleMFRC522()

while True:
lcd.clear()
lcd.message(“Ready for card.”)

try:
id, text = reader.read()
print(id)
print(text)
lcd.clear()
lcd.message(text)
val = (text, id)
mycursor.execute(sql, val)
mydb.commit()
sleep(3)

GPIO.cleanup()
