Management Information System (MIS) Practice Exam

Which of the following specialized scanners is used to scan human body characteristics for identification and security purposes?

1. biometric scanner

2. optical scanner

3. bar code scanner

4. smart card scanner

The correct answer is: biometric scanner

The use of a biometric scanner is specifically designed to capture human body characteristics, such as fingerprints, facial features, iris patterns, or voice patterns, for the purposes of identification and security. These scanners analyze physical or behavioral traits that are unique to each individual, which makes them highly effective for secure access control and identity verification. In contrast, an optical scanner primarily digitizes physical documents or images rather than scanning human characteristics, while a barcode scanner is utilized for reading barcodes to identify products or inventory items. A smart card scanner reads information stored on smart cards, which are used for various applications like access control or payment systems, but it does not scan human body characteristics. Therefore, the characteristics and applications of biometric scanners make them the correct choice for the question about identifying and securing human body traits.
