California Code, Business and Professions Code - BPC § 7529

(a)(1) Upon the issuance of and with each biennial renewal of a license, a license in the form of an enhanced photo identification card of the size, design, and content as may be determined by the director or the director's designee shall be issued by the bureau to each licensee, as follows:

(2) The enhanced photo identification card is evidence that the licensee is licensed pursuant to this chapter. The card shall contain the name of the licensee, license expiration date, and a photograph of the licensee. The enhanced photo identification card shall clearly state that the person is licensed as a private investigator or is the qualified manager or officer of the licensee. The enhanced photo identification card is to be composed of a durable material and may incorporate technologically advanced security features. The bureau may recover its costs in an amount sufficient to reimburse the department's costs for furnishing the enhanced photo identification card. The fee charged shall not exceed the actual direct costs for system development, maintenance, and processing necessary to provide this service. The total amount of costs shall be recovered by including that amount in the fee charged for the initial application of and renewal of licensure. When the position, office, or association with a licensee belonging to a person to whom a card is issued is terminated, the person shall surrender the card to the licensee and, within five days thereafter, the licensee shall mail or deliver the card to the bureau for cancellation. Every person, while engaged in any activity for which licensure is required, shall display the person's valid enhanced photo identification card as provided by regulation.
