"Barnes & Noble Inc. said Tuesday that devices used by customers to
swipe credit and debit cards have been tampered with in 63 of its
stores in nine states. The company warned customers to check for
unauthorized transactions and to change their personal identification
numbers, or PINs. It didn't say how many accounts may have been
compromised. But The New York Times, citing a high-ranking company
official it did not name, reported that hackers had made unauthorized
purchases on some customer credit cards."
