After I connected the keyboard reader, I set the card plus password. After swiping the card, the card reader buzzer will beep continuously until the password is entered. It's annoying on that way. Many other controllers can be connected to the LED light control line of the card reader, so after swiping the card, the card reader light will keep flashing, prompting to enter the password, and the buzzer will not keep beeping. Hope we can improve it too.

Hello, thank you for using our company's products, after setting the card and password to open the door, swiping the card, the buzzer of the card reader will sound once, then enter the password, and the buzzer will also sound when you press the keyboard keys.
