All persons to whom such license certificates, pocket cards, shields or badges shall have been issued shall be responsible for the safe keeping of the same, and shall not loan, let or allow any other person to use, wear or display such certificate, pocket card, shield or badge. No person shall wear or display any license certificate, pocket card, shield or badge, purporting to authorize the holder or wearer thereof to act as a private detective or investigator, unless the same shall have been duly issued pursuant to the provisions of this act.

No person, except as authorized in this section, shall wear or display a shield or badge of any design or material, purporting to indicate that the wearer or bearer thereof is a private detective or investigator or is authorized to act as a private detective or investigator, unless required by law to do so. Any person violating the provisions of this section shall be guilty of a misdemeanor, and, upon conviction thereof, shall be sentenced to pay a fine of not more than five hundred dollars ($500) or to undergo imprisonment for not more than one (1) year or both.
