Cal. Penal Code § 484h

Every retailer or other person who, with intent to defraud: (a) Furnishes money, goods, services or anything else of value upon presentation of an access card obtained or retained in violation of Section 484e or an access card which he or she knows is a counterfeit access card or is forged, expired, or revoked, and who receives any payment therefor, is guilty of theft. If the payment received by the retailer or other person for all money, goods, services, and other things of value furnished in violation of this section exceeds nine hundred fifty dollars ($950) in any consecutive six-month period, then the same shall constitute grand theft. (b) Presents for payment a sales slip or other evidence of an access card transaction, and receives payment therefor, without furnishing in the transaction money, goods, services, or anything else of value that is equal in value to the amount of the sales slip or other evidence of an access card transaction, is guilty of theft. If the difference between the value of all money, goods, services, and anything else of value actually furnished and the payment or payments received by the retailer or other person therefor upon presentation of a sales slip or other evidence of an access card transaction exceeds nine hundred fifty dollars ($950) in any consecutive six-month period, then the same shall constitute grand theft.
