California Code, Business and Professions Code - BPC § 7582.13

Upon the issuance of a license, a pocket card of the size, design, and content determined by the director shall be issued to each licensee, if an individual, or if the licensee is a person other than an individual, to its manager and to each of its officers and partners.  The pocket card is evidence that the licensee is licensed pursuant to this chapter.  The card shall contain the signature of the licensee, signature of the chief, and a photograph of the licensee, or bearer of the card, if the licensee is other than an individual.  The card shall clearly state that the person is licensed as a private patrol operator or is the manager or officer of the licensee.  The applicant may request to be issued an enhanced pocket card that shall be composed of a durable material and may incorporate technologically advanced security features.  The bureau may charge a fee sufficient to reimburse the department's costs for furnishing the enhanced pocket card.  The fee charged may not exceed the actual costs for system development, maintenance, and processing necessary to provide this service, and may not exceed six dollars ($6).  If the applicant does not request an enhanced card, the department shall issue a standard card at no cost.  When a person to whom a card is issued terminates his or her position, office, or association with the licensee, the card shall be surrendered to the licensee and within five days thereafter shall be mailed or delivered by the licensee to the bureau for cancellation.  Every person, while engaged in any activity for which registration is required, shall display their valid pocket card as provided by regulation.
