1747.02.  
As used in this title:
(a) “Credit card” means any card, plate, coupon book, or other single credit device existing for the purpose of being used from time to time upon presentation to obtain money, property, labor, or services on credit. “Credit card” does not mean any of the following:
(1) Any
 single credit device used to obtain telephone property, labor, or services in any transaction under public utility tariffs.
(2) Any device that may be used to obtain credit pursuant to an electronic fund transfer, but only if the credit is obtained under an agreement between a consumer and a financial institution to extend credit when the consumer’s asset account is overdrawn or to maintain a specified minimum balance in the consumer’s asset account.
(3) Any key or card key used at an automated dispensing outlet to obtain or purchase petroleum products, as defined in subdivision (c) of Section 13401 of the Business and Professions Code, that will be used primarily for business rather than personal or family purposes.
(b) “Accepted credit card” means any credit card that the cardholder has requested or applied for and
 received or has signed, or has used, or has authorized another person to use, for the purpose of obtaining money, property, labor, or services on credit. Any credit card issued in renewal of, or in substitution for, an accepted credit card becomes an accepted credit card when received by the cardholder, whether the credit card is issued by the same or a successor card issuer.
(c) “Card issuer” means any person who issues a credit card or the agent of that person for that purpose with respect to the credit card.
(d) “Cardholder” means a natural person to whom a credit card is issued for consumer credit purposes, or a natural person who has agreed with the card issuer to pay consumer credit obligations arising from the issuance of a credit card to another natural person. For purposes of Sections 1747.05, 1747.10, and 1747.20, the term includes any person to whom a credit card is
 issued for any purpose, including business, commercial, or agricultural use, or a person who has agreed with the card issuer to pay obligations arising from the issuance of that credit card to another person.
(e) “Retailer” means every person other than a card issuer who furnishes money, goods, services, or anything else of value upon presentation of a credit card by a cardholder. “Retailer” shall not mean the state, a county, city, city and county, or any other public agency.
(f) “Unauthorized use” means the use of a credit card by a person, other than the cardholder, (1) who does not have actual, implied, or apparent authority for that use and (2) from which the cardholder receives no benefit. “Unauthorized use” does not include the use of a credit card by a person who has been given authority by the cardholder to use the credit card. Any attempted termination by the cardholder
 of the person’s authority is ineffective as against the card issuer until the cardholder complies with the procedures required by the card issuer to terminate that authority. Notwithstanding the above, following the card issuer’s receipt of oral or written notice from a cardholder indicating that it wishes to terminate the authority of a previously authorized user of a credit card, the card issuer shall follow its usual procedures for precluding any further use of a credit card by an unauthorized person.
(g) An “inquiry” is a writing that is posted by mail to the address of the card issuer to which payments are normally tendered, unless another address is specifically indicated on the statement for that purpose, then to that other address, and that is received by the card issuer no later than 60 days after the card issuer transmitted the first periodic statement that reflects the alleged billing error, and that does all of the following:
(1) Sets forth sufficient information to enable the card issuer to identify the cardholder and the account.
(2) Sufficiently identifies the billing error.
(3) Sets forth information providing the basis for the cardholder’s belief that the billing error exists.
(h) A “response” is a writing that is responsive to an inquiry and mailed to the cardholder’s address last known to the card issuer.
(i) A “timely response” is a response that is mailed within two complete billing cycles, but in no event later than 90 days, after the card issuer receives an inquiry.
(j) A “billing error” means an error by omission or commission in (1)
 posting any debit or credit, or (2) in computation or similar error of an accounting nature contained in a statement given to the cardholder by the card issuer. A “billing error” does not mean any dispute with respect to value, quality, or quantity of goods, services, or other benefit obtained through use of a credit card.
(k) “Adequate notice” means a printed notice to a cardholder that sets forth the pertinent facts clearly and conspicuously so that a person against whom it is to operate could reasonably be expected to have noticed it and understood its meaning.
(l) “Secured credit card” means any credit card issued under an agreement or other instrument that pledges, hypothecates, or places a lien on real property or money or other personal property to secure the cardholder’s obligations to the card issuer.
(m) “Student credit card” means any credit card that is provided to a student at a public or private college or university and is provided to that student solely based on his or her enrollment in a public or private university, or is provided to a student who would not otherwise qualify for that credit card on the basis of his or her income. A “student credit card” does not include a credit card issued to a student who has a cocardholder or cosigner who would otherwise qualify for a credit card other than a student credit card.
(n) “Retail motor fuel dispenser” means a device that dispenses fuel that is used to power internal combustion engines, including motor vehicle engines, that processes the sale of fuel through a remote electronic payment system, and that is in a location where an employee or other agent of the seller is not present.
