Debit cards: service fees.

Existing law prohibits a retailer from imposing a surcharge on a credit cardholder who elects to use a credit card instead of paying by cash, check or similar means, as provided. Existing law also provides that any retailer who imposes a surcharge and who fails to pay that amount to the cardholder within 30 days of written demand is liable for 3 times the amount at which actual damages are assessed. The cardholder is entitled to recover reasonable attorney's fees and costs incurred in the action. Existing law exempts from these provisions charges for payment made to an electrical, gas, or water corporation. Existing law also regulates the use of debit cards, as defined.
