By Tom Lehman 5:54pm, December 19, 2013 - Updated 5:59pm, December 19, 2013Target says a technical problem has compromised the credit and debit card information of as many as 40 million accounts, but technology experts say there are measures that can be used to prevent unauthorized purchases.
Accounts affected by the data breach include those of customers who swiped their cards at U.S. Target stores between November 27th and December 15th, according to the chain.
The stolen data includes customer names, credit and debit card numbers, card expiration dates and the three-digit security codes located on the backs of cards.
CBS News and CNET Technology Analyst Larry Magid told Delaware's News at Noon that Target shoppers should check the most recent account statements on their debit and credit cards if they believe they may be affected..
"Check that and if you see anything that looks suspicious, contact (your card company)," Magid said. "The nice thing about credit cards is that they are required to suspend a bill if there's any questions until it's resolved."
He says you can ask your card company to put a fraud alert on your account to add an extra layer of security against unauthorized purchases.
