Assistant Laboratory Animal Technician (ALAT) Practice Exam

Which device is designed to identify individuals based on unique physical traits?

1. Keycard readers

2. Biometric scanners

3. Facial recognition cameras

4. Security cameras

The correct answer is: Biometric scanners

Biometric scanners are specifically designed to identify individuals by analyzing unique physical traits, such as fingerprints, facial patterns, iris structures, or voice recognition. This technology relies on the distinct characteristics that make each individual unique, offering a high level of security and accuracy in identification. While facial recognition cameras can be used to identify individuals based on facial features, they are a subset of biometric technology, focusing solely on the face. In comparison, biometric scanners encompass a broader range of identification methods beyond just facial recognition. Keycard readers utilize cards that contain specific information for access control, but they do not identify based on physical traits. Security cameras provide surveillance and can capture images, but they do not inherently have the capability to identify individuals based on unique physical characteristics. Thus, the choice of biometric scanners captures the full scope of identifying individuals by their inherent biological traits, making it the most accurate answer to the question.
