Biometrics Questions
Biometric access cards are a type of identification card that incorporates biometric technology for secure access control. The process of using biometric access cards involves the following steps:
1. Enrollment: The individual's biometric data, such as fingerprints, iris patterns, or facial features, is captured and stored in a secure database. This process may require the person to provide multiple samples to ensure accuracy and reliability.
2. Card issuance: Once the biometric data is enrolled, a unique identifier is assigned to the individual, and a biometric access card is issued. This card typically contains a microchip or magnetic stripe that stores the individual's biometric template and other relevant information.
3. Authentication: To gain access to a secured area or system, the individual presents their biometric access card to a card reader. The card reader then verifies the authenticity of the card and prompts the individual to provide their biometric sample.
4. Biometric verification: The individual's biometric sample, such as a fingerprint or iris scan, is captured by the card reader and compared against the stored template on the card. If the biometric sample matches the template within an acceptable threshold, access is granted.
5. Access control: Upon successful verification, the individual is granted access to the desired area or system. This can involve unlocking doors, activating turnstiles, or granting permission to use specific resources.
6. Audit trail: Biometric access cards often include a logging system that records each access attempt, including the date, time, and outcome. This audit trail helps monitor and track access activities for security purposes.
Overall, the process of biometric access cards combines the use of biometric technology, secure storage of biometric templates, and card-based authentication to provide a reliable and secure method of access control.
