Dab tsi yog cov function ntawm ib RFID Key Fob thiab seb nws txawv ntawm ib 125khz RFID Key Fob?

ib qho rfid fob tshuab Tsim los pab kom muaj kev ruaj ntseg rau vaj tse los yog tsheb. It uses radio frequency identification to transmit a unique code to a reader, allowing authorized individuals to gain entry. The 125khz RFID key fob operates at a lower frequency than other RFID key fobs, offering a different level of security.

Combination of key fobs and biometric authentication

Biometric authentication, as an important way of modern security authentication, verifies identity based on the user’s unique biometric features (such as fingerprints, iris scans, and voiceprints). Compared with traditional password authentication, biometric authentication has higher security and convenience because biometric features are unique to each person and difficult to copy or imitate.

The role of key fobs in biometric authentication:

• Integrate biometric technology: Some advanced key fobs have integrated biometric authentication technology, such as fingerprint recognition. Users can not only authenticate physically through the key fob but also through its built-in biometric recognition module.
• Enhanced security: By integrating biometric authentication into the key fob, users can get additional security protection. Even if the key fob is lost or stolen, unauthorized users cannot access protected resources by simple copying or imitation.
• Verification process: When users need to use the key fob for authentication, they need to follow the device’s requirements. For fingerprint recognition, users may need to place their fingers on the fingerprint recognition area of ​​the key fob to let the device read the fingerprint ridges and seven layers of skin information of the fingertips. The device then compares the information it reads with a pre-stored template to verify the user’s identity.
• Convenience: Although biometric authentication adds security, it does not sacrifice convenience. Instead of having to remember complex passwords or carry additional authentication devices, users can simply use the key fob they carry with them to complete authentication.

The combination of key fob and biometric authentication provides users with an additional level of security protection. By integrating biometric authentication technology, the key fob becomes not only a simple physical authentication tool but also a powerful digital authentication solution. This combination allows users to enjoy higher security while maintaining convenience.

What are the benefits of key fobs?

The benefits of key fobs are mainly reflected in the security and convenience they provide. The following are the specific benefits:

Enhanced security:

As a physical authentication device, key fobs make it more difficult for attackers to gain access. Attackers not only need to obtain the user’s password but also need to physically possess the key fob to access the system or network.

Key fobs can generate one-time random passwords that expire after a fixed time, effectively preventing passwords from being reused or abused after being intercepted.

Key fobs support multi-factor authentication (MFA), which further enhances the security of the system by combining other verification factors (such as passwords, biometrics, li ntawd.).

Higher convenience:

Users do not need to remember complex passwords or carry additional authentication devices. They only need to carry daily key fobs to complete authentication, which greatly simplifies the login process.
Key fobs usually have a simple and intuitive user interface, which reduces the user’s learning cost and difficulty of operation.

Flexible management:

Administrators can remotely program and manage multiple key fobs through back-end software to achieve flexible control of user access rights.

Multiple access levels can be created to grant or deny access to networks, facilities, or equipment according to the needs and permissions of different users.
Through communication with RFID readers, the use of key cards can be monitored and managed in real-time, and potential security risks can be discovered and handled in a timely manner.

Wide applicability:

Key cards are suitable for various commercial facilities, including factories, offices, restricted areas (such as server rooms), laboratories hospitals, li ntawd., and can meet security needs in different scenarios.
Key cards can be integrated with other security systems (such as video surveillance systems, alarm systems, li ntawd.) to achieve more comprehensive security protection.

High reliability:

Key cards usually have a long service life and stable performance and can work reliably in various environments.
Key cards use advanced encryption technology to ensure the security of data transmission and storage.
