(1) Personnel identification media that -
(i) Convey a full face image, full name, employer, and identification number of the individual to whom the identification medium is issued;
(ii) Indicate clearly the scope of the individual's access and movement privileges;
(iii) Indicate clearly an expiration date; and
(iv) Are of sufficient size and appearance as to be readily observable for challenge purposes.
(2) Procedures to ensure that each individual in the secured area or SIDA continuously displays the identification medium issued to that individual on the outermost garment above waist level, or is under escort.
(3) Procedures to ensure accountability through the following:
(i) Retrieving expired identification media.
(ii) Reporting lost or stolen identification media.
(iii) Securing unissued identification media stock and supplies.
(iv) Auditing the system at a minimum of once a year, or sooner, as necessary to ensure the integrity and accountability of all identification media.

(vi) Ensure that only one identification medium is issued to an individual at a time. A replacement identification medium may only be issued if an individual declares in writing that the medium has been lost or stolen.
(b) The aircraft operator may request approval of a temporary identification media system that meets the standards in § 1542.211(b) of this chapter, or may arrange with the airport to use temporary airport identification media in accordance with that section.
