Recently, several large retail chains have started offering customers the option to receive electronic receipts for in-store purchasers, as the New York Times reports. For instance, a cashier may ask a customer for his or her email address at check-out and then email the receipt to the customer. Paperless receipt programs offer retailers new and exciting marketing opportunities–for instance, adding a retail store purchaser’s email address to the company’s customer relationship management database, even if that customer never shops online. But with these new opportunities come potential liabilities from old laws that were not written with this new technology in mind.

On December 19, 2008, in Party City Corp. v. The Superior Court of San Diego County, the California Court of Appeal in the Fourth Appellate District held that zip codes are not “personal identification information” under California’s Song-Beverly Credit Card Act of 1971, California Civil Code Sec. 1747.08 (the “Act.”). The Act prohibits a retailer that accepts credit cards from, among other things, “request[ing], or require[ing] as a condition to accepting the credit card as payment in full or in part for goods or services, the cardholder to provide personal identification information, which the [retailer] writes, causes to be written, or otherwise records upon the credit card transaction form or otherwise.” Id. at § 1748.08(a)(2). Under the Act, “personal identification information” is “information concerning the cardholder, other than information set forth on the credit card, and including, but not limited to, the cardholder’s address and telephone number.” Id. at § 1747.08(b). Subdivision (e) of the statute provides that “[a]ny person who violates this section shall be subject to a civil penalty not to exceed two hundred fifty dollars ($250) for the first violation and one thousand dollars ($1,000) for each subsequent violation, to be assessed and collected in a civil action brought by the person paying with a credit card, by the Attorney General, or by the district attorney or city attorney of the county or city in which the violation occurred.”
