An ID card portrays authentication based upon something the user has.
Not always. Authentication is based upon one or more of the following:Something the user knows (such as a PIN).Something the user has (such as an ID card).Something the user is (such as a fingerprint).
An ATM card is an example of "something you have" authentication. This type of authentication relies on a physical item, such as a card, that the user possesses to gain access to their bank account and perform transactions. It is often used in conjunction with a PIN (Personal Identification Number), which adds an additional layer of security by requiring "something you know" authentication as well.

Yes. Any biometric reading, such as a fingerprint, retina scan or DNA sample portrays authentication based upon something the user is.
You cannot portray identification upon something unknown. It must be something known only to the user, or be something the user is (such as a fingerprint, retina scan or DNA sample) or something the user has (such as an ID card).

Authentication based on something the user has, combined with a PIN, is known as two-factor authentication (2FA). This method requires a user to provide a physical object, such as a security token or a smartphone app, along with a personal identification number (PIN) to verify their identity. This adds an additional layer of security, as even if someone obtains the PIN, they would still need the physical device to gain access. Such a system helps protect against unauthorized access and enhances overall security.
Two-step authentication is a security process that requires users to provide two different forms of identification before accessing an account or system. Typically, this involves something the user knows (like a password) and something the user has (such as a smartphone or authentication app that generates a one-time code). This added layer of security helps protect against unauthorized access, even if the password is compromised.
