What Are the Types of Double-Sided Fingerprint Locks?

Double-sided fingerprint locks are a type of smart security device that allows access from both sides of a door using biometric recognition. They are commonly used in residential, commercial, and office settings to provide controlled entry while maintaining convenience and safety. These locks combine fingerprint scanning technology with secure locking mechanisms, enabling users to manage access without traditional keys.

Full Biometric Double-Sided Fingerprint Locks

Full biometric double-sided fingerprint locks rely exclusively on fingerprint recognition for access. These locks have sensors on both sides of the door, allowing authorized users to unlock the door by scanning their fingerprints from either side.

The primary function of these locks is to provide secure and keyless entry. They are suitable for environments where multiple people need access, such as offices, shared apartments, or secure rooms. Some models include memory storage for a large number of fingerprints, allowing management of multiple users. Additionally, these locks often include anti-tamper features to prevent unauthorized access. Full biometric locks are convenient for locations where users want to avoid carrying physical keys while maintaining security.

Fingerprint and Key Combination Locks

Fingerprint and key combination double-sided locks integrate fingerprint recognition with a traditional mechanical key as a backup. This design ensures that access is maintained even if the biometric system fails due to low battery or technical issues.

The primary function of this type is to combine modern convenience with the reliability of conventional locking methods. Users can unlock the door with a fingerprint under normal circumstances or use the key as an alternative. These locks are commonly used in residential settings or commercial environments where access control needs to balance security with reliability. The key function also provides peace of mind in emergencies, ensuring that access is always possible.

Fingerprint and Password Double-Sided Locks

Fingerprint and password double-sided locks provide multiple access methods: biometric recognition and numeric code entry. Users can unlock the door using a fingerprint or by entering a pre-set password.

The function of this type is to increase flexibility in access control. It allows temporary access for guests or employees without registering their fingerprints. Password entry is also helpful in situations where the fingerprint sensor may be less responsive, such as wet or dirty fingers. These locks are often used in offices, shared housing, and public facilities, providing convenience while maintaining a controlled and secure environment.

Smart Double-Sided Fingerprint Locks with Mobile Connectivity

Smart double-sided fingerprint locks are equipped with wireless or Bluetooth connectivity, allowing users to control access remotely using a smartphone or other smart device. These locks often integrate fingerprint recognition with additional features such as temporary digital keys, notifications, and access logs.

The primary function of smart locks is to provide both physical security and remote management. Users can monitor who enters or exits, grant temporary access, or lock and unlock doors without being physically present. These locks are suitable for modern homes, offices, or rental properties where convenience, control, and monitoring are important. The combination of double-sided fingerprint recognition and smart connectivity enhances both security and usability.
