 Smart card and PIN are the examples of multifactor authentication. Multifactor authentication is a security method that requires two or more factors or pieces of evidence to verify the identity of a user or device. The factors are usually classified into three categories: something you know (such as a password or PIN), something you have (such as a smart card or token), or something you are (such as a fingerprint or retina scan). Multifactor authentication provides stronger security than single-factor authentication because it reduces the risk of compromise if one factor is lost or stolen. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 207.
