This is the RC522 RFID Dual Component Module for Arduino. RC522 reads cards at 13.56MHz. This product is available with both straight and angled Berg connectors depending on the application. of them work with SSD1306 OLED display and 8-relay module. The relay is normally connected to a door lock solenoid (not shown). When the correct card is read, the relay activates the electromagnet and the door unlocks. The wrong card keeps the door closed and sends an SMS to security. These modules allow you to control/restrict/monitor access. a few ideas. Order your own set now and let's see what you make!
