Explanation : A fingerprint scanner is the most common example of biometric security. Biometric security identifies a user by a biological trait. Biometric devices include devices such as fingerprint scanners, retinal scanners, and voice recognition devices. Of these, a fingerprint scanner is the most common.
User name and password is not an example of biometric security. However, user name and password is the most commonly used network authentication method.
A smart card and reader is not an example of a biometric security device, but it is an example of security hardware. To use a smart card, the user inserts the smart card into a reader and then supplies a password or personal identification number (PIN) when prompted.
A fob is not an example of a biometric security device, but it is an example of security hardware. The fob automatically generates a number that is used for authentication. The user might or might not also be required to provide a user name and password.
