Barnes & Noble says hackers may have stolen customer data
Barnes & Noble, the country's largest bookseller, said data thieves hacked into payment devices and may have stolen customer credit and debit card information at 63 of its stores nationwide, including 20 in California.
Hackers planted bugs in a single card reader at each of the stores, the company said. Customers swipe their payment cards through the machines and, if using a debit card, enter their personal identification number.
Those PINs may be at risk, along with other account information, potentially giving thieves access to customers' private accounts. Among the California locations hit were stores in Calabasas, San Diego and Chula Vista.
