6.1 Unlocking Methods
The keypad supports three primary methods for unlocking the door:
- RFID Card Unlocking: Present a pre-programmed RFID card to the card reading area on the keypad. The door will unlock if the card is valid.
- Password Unlocking: Enter your programmed password followed by the '#' key. The door will unlock if the password is correct.
- RFID Card + Password Unlocking: For higher security, present your RFID card to the reading area, then enter your programmed password followed by the '#' key. The door will unlock only if both are valid.
