What phrase is found on the line where one signs their name on new E passports?

The correct phrase found on the line where one signs their name on new e-passports is "Signature or bearer." This designation indicates that the signature should belong to the passport holder, reinforcing the document's authenticity and the identity of the individual who is claiming the passport's ownership. This phrase serves a dual purpose: it allows for the inclusion of a signature while also acknowledging that the passport is issued to and is the property of the bearer.

By using the phrase "or bearer," it clarifies that the passport must be presented by the individual to whom it is issued, thereby enhancing security against unauthorized use. This measure is especially relevant in border security and control, where verifying the identity of travelers is essential.

The other options do not accurately represent the phrase used in e-passports, as they either suggest a more limited scope ("Signature only") or mischaracterize the significance of the signature ("Official Signature" or "Name of bearer"). Consequently, the phrase "Signature or bearer" effectively conveys the necessary information for identification and accountability in passport usage.
