    Spending and withdrawal limits imposed by Chase bank in response to the Target security breach are leaving many shoppers frustrated. NBC 5’s Christian Farr spoke to a Hoffman Estates couple who had their card declined while shopping. They say the limits are designed to protect Chase, not its customers.

    Target says customers' encrypted PIN data was removed during the massive data breach that occurred earlier this month.

    Previously Target had said that encrypted data was stolen but stopped short of identifying it as PIN numbers. But the company issued a statement Friday that additional forensic work has shown that encrypted PIN data was removed along with customers' names and card numbers.

    "We remain confident that PIN numbers are safe and secure," said spokeswoman Molly Snyder in an emailed statement. "The PIN information was fully encrypted at the keypad, remained encrypted within our system, and remained encrypted when it was removed from our systems."

    Some Target customers say they'll stay away from the retailer, until they're sure a credit card security breach has been dealt with. Christan Farr reports.

    A PIN number is the personal identification code used to make secure transactions on a credit or debit card.

    Data connected to about 40 million credit and debit cards used at Target were stolen between Nov. 27 and Dec. 15.

    One Target customer who found a big fraudulent charge on her credit card doubts she'll shop there any time soon. Christian Farr reports on what the experts say you should do to protect yourself.

    Security experts say it's the second-largest theft of card accounts in U.S. history, surpassed only by a scam that began in 2005 involving retailer TJX Cos. In addition to the encrypted PIN numbers, the stolen data from Target included customer names, credit and debit card numbers, card expiration dates and the embedded code on the magnetic strip on back of the card.

    Still, Target said it believes the PIN numbers are still safe because the information was strongly encrypted. The retailer said that PIN information is encrypted within its systems and can only be decrypted when it is received by its external, independent payment processor

    "The most important thing for our guests to know is that their debit card accounts have not been compromised due to the encrypted PIN numbers being taken," Snyder said.

    Minneapolis-based Target said it is still in the early stages of investigating the breach. It has been working with the Secret Service and the Department of Justice.
