What characteristics must acceptable identification documents generally have?

Acceptable identification documents are required to have specific characteristics to ensure the legitimacy and identity of the individual presenting them. Generally, a valid form of ID must include a signature and a photograph of the individual. The inclusion of a photograph serves to visually verify the identity of the person, while the signature allows for a comparison with the signature provided on any documents the notary might be officiating. These elements are important in preventing fraud and ensuring that the notary is confident in the identity of the signer.

Other options like a bar code and user ID are not standard requirements for identification used in notary processes, and while a signature is important, it must be accompanied by other identifying features, such as a photograph, to be considered reliable. Birthdate and birthplace also do not adequately serve to verify identity in the context of notary services, as they can be found on various documents and do not provide a direct verification of the individual's current identity. Thus, the requirement of both a signature and a photograph is critical for acceptable identification in notarial acts.
