wiredmikey writes: After saying earlier this week that it was investigating reports of a data breach related to payment cards used at its locations, P.F. Chang's China Bistro confirmed on Thursday that credit and debit card data has been stolen from some of its restaurants. What's interesting, and somewhat humorous, is that the company said that it has switched over to manual credit card imprinting systems for all of its restaurants located in the continental United States. The popular restaurant chain said that on Tuesday, June 10, the United States Secret Services alerted the company about the incident. Admitting that it does not know the extent or current situation and impact of the attack, the company noted in a statement: "All P.F. Chang's China Bistro branded restaurants in the continental U.S. are using manual credit card imprinting devices to handle our credit and debit card transactions," the company said. "This allows you to use your credit and debit cards safely. If it's not obvious, anyone who has visited a P.F. Chang's and used a payment card in the last several months should monitor their accounts and report any suspected fraudulent activity to their card company.
