Right in the middle of holiday shopping season, some 40 million credit and debit card numbers were stolen in a major breach of Target customer data. The thefts occurred in stores, not online. Target says it's working with a forensics company to investigate and prevent similar data thefts from occurring in the future. Security experts say one way to limit them is to switch from magnetic stripes on cards to embedded chips.
