  1. Multiple Access Methods

Fingerprint door locks offer various access methods to accommodate different scenarios:

  • Fingerprint: The primary method, where a registered fingerprint is recognised for access.
  • PIN Code: Many locks have a keypad for entering a numeric PIN code as an alternative access method.
  • Key: Some locks include a traditional key as a backup in case of fingerprint recognition failure.
  1. Smart Features

Modern fingerprint door locks often come with smart features, making them more versatile and convenient:

  • Remote Access: Smart locks can be controlled remotely through a smartphone app. This allows you to grant access to visitors or lock/unlock the door from anywhere.

  • Access Logs: Smart locks keep a record of who accessed the door and when, providing security and monitoring capabilities.
  1. User Management

User management is an essential feature for fingerprint door locks, allowing you to control and customise access:

  • Adding and Removing Users: Easily add and remove authorised users, making it simple to grant temporary access to guests or service providers.
  • User Profiles: Some locks allow you to create user profiles with specific access rights and schedules.
  • Access Permissions: You can specify which fingers are authorised for access, further enhancing security.
  1. Security Features

To ensure the utmost security, fingerprint door locks include several protective features:

  • Tamper Detection: Locks can detect tampering attempts and trigger alarms or notifications.
  • Anti-Scratch and Anti-Spoofing: Some locks include anti-scratch and anti-spoofing technologies to prevent unauthorised access via forged fingerprints or photos.
  • Auto-Locking: Smart locks can automatically lock the door after a certain period, preventing accidental or intentional breaches.

Consider the installation process and compatibility with your door:

  • Installation: Determine whether the lock is suitable for DIY installation or if professional installation is recommended.
  • Door Compatibility: Ensure the lock is compatible with the type and thickness of your door.
  1. Warranty and Support

Check the manufacturer’s warranty and customer support options to ensure peace of mind and assistance if issues arise.
