Restaurant chain P.F. Chang's China Bistro says the theft of credit and debit card information from some of its restaurants earlier this year was "part of a highly sophisticated criminal operation."
P.F. Chang's China Bistro confirmed on Thursday credit and debit card data was stolen from its restaurants, saying it is switching in the meantime to a manual imprinting system to process cards safety.
A large batch of stolen credit card numbers for sale on an underground forum may have come from a breach at P.F. Chang's China Bistro, a US restaurant chain that said on Tuesday it is investigating.
