Make your own Access Control System by using a RFID-RC522 mifare reader in combination with an 4x3 membrane keypad!
What's the different between the already existing tutorials?
- Multiple mifare cards
- Reading out the UID number and program this UID in the Arduino
- Six or four digit Pincode's
- The combining of a UID number with an Pincode.
- Detecting wrong Pincode's
- Setting up an Timelimit for entering Pincode.
In this article, I will show you how to create it!
Read this tutorial or watch the youtube video :)

Step 4: Arduino Code
Download & import the MRFC Library and the Keypad Library.
The SPI library is already present in your Arduino Software.
Download the sketch & upload it to your Arduino.
Arduino Code and library's also available at:
Step 5: Endresult
You have now created your own Acces Control System!
Watch the video for the result :)
