User's Manual

• The device should make a beep sound which means the RFID has
been read and the buttons can now be pressed.
• In case the user does not swipe/scan the RFID card, the button
presses will not be sent through to the server.
• Each button press will be accompanied by a buzzer(beep) sound
and a blue LED on the button pressed to indicate successful
recognition of the event.
• Each RFID scan is valid for 30 seconds, meaning after the user
scans the RFID card, the buttons can be pressed for 30 seconds
after which the user will have to swipe the card again. However, a
different RFID card can be used instantaneously which would then
be valid for another 30 seconds.
