• Each button press is accompanied by a buzzer sound and a BLUE
LED blink over the button pressed to indicate the button press
recognition.
• Each RFID scan will be valid for 30 seconds, meaning after the user
scan the RFID card, the button press window is 30 seconds after
which the user will again have to scan/swipe the RFID card.
However, a different RFID card can be scanned instantaneously
which would then be valid for another 30 seconds.
