The project relies on the built-in Wi-Fi module of the Arduino Yun, and the microcontroller is connected to the sensors and RFID reader modules alongside an electronic strike to lock/unlock the door.

There’s a library, but you have to change over your Arduino to use USB 2.1. It turns ... He also decided against RFID but didn’t really say why. NFC business cards are a thing.
