4.2 Advanced Security Features
- Combination Unlocking: For enhanced security, configure the lock to require two unlocking methods (e.g., RFID card + password) to open the door.

- Automatic Lock: The lock features an automatic retraction and ejection of the latch, ensuring the door is securely locked after closing.
- Secure Encryption Chip: The lock incorporates a secure encryption chip to protect biometric data and prevent jamming or cracking attempts.
