What type of reader grants access based on unique individual features?

• A. Card reader
• B. Magnetic reader
• C. Biometric reader
• D. Keypad entry

Answer: (C)

A biometric reader is designed to grant access by analyzing unique individual features, such as fingerprints, facial recognition, iris patterns, or voice recognition. These identifying traits are specific to each individual, making biometric systems highly secure and difficult to replicate.

In contrast, card readers and magnetic readers rely on physical cards or magnetic strips that can be lost, stolen, or duplicated, which compromises security. Keypad entry systems require the user to remember a code or password, which can also be forgotten or shared. The key aspect of biometric technology is its reliance on inherent and personal attributes, which adds an additional layer of security that is not present in the other types of readers.
