I saw your message. I am busy so I can't help you with the code. Take a look to these steps that can help you making this project :
1. Put the SPI, MFRC522 and servo library;
2. You'll need two cards : one accepted and one denied. You can scan a NFC card to have the code of it. (the card that will be accepted)
3. You will make an "if" that said something like "if the scanned card has the accepted code , servo will be open".
Good luck with the project! :)
Ok , I will add a resistor soon and thank you for this suggestion ! :)
