Uses: Remote visitor access, keyless handover for short-term rentals, temporary use in public areas, and automatic tracking.
2. Bluetooth Unlocking

Uses: Hands-free home use, access in environments without network (basement/villa), and the ability to revoke shared access permissions at any time.
3. PIN Code Unlocking
Function: Supports fixed/temporary (limited-time) PINs, multiple PINs, and automatic locking after too many incorrect attempts.
Uses: Convenient for the elderly and children, temporary authorization for caregivers/construction workers (expiring upon expiration), and emergency access when the phone is out of battery or the card is missing.
4. Card Swiping Unlocking
Function: Compatible with RFID cards, unlocks with a simple swipe, batch entry/quick deregistration.

II. Key Advantages
1.
Convenience: Multi-mode compatibility for all users: mobile phones (Bluetooth/QR code), cards, passwords, covering young people, the elderly, children, and visitors.
