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).
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).

1. Fingerprint.
Authentication is based upon either:Something you know (such as a PIN).Something you have (such as an ID card).Something you are (such as a fingerprint, retina scan or DNA sample).Preferably, authentication will combine two or more of the three.

Yes.
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.
RADIUS requires port-based authentication.
