Santa may be checking his list twice, but you definitely should be checking your credit and debit cards twice this holiday season.  Target announced a security breach may have compromised some 40 million credit and debit card accounts.

Target is asking customers to be vigilant with their statements even if you haven't noticed any suspicious activity.  Many shoppers we talked with aren't happy to hear about the security breach but at the same time they aren't surprised. 

"It's frightening," said Rancho Mirage resident Karen Kaess.

Going to the store is supposed to be safer than shopping online.

"I don't think anything is secure anymore," said Rancho Mirage resident Joan Kipatrick.

As many as 40 million people who shopped at target between November 27th and December 15th, may have had their credit or debit card information stolen.  Hackers seem to have lifted shoppers' personal information as they swiped their credit cards at thousands of Target store registers across the country.

"It's the season, the holiday season and so people are always out shopping and it's a great time to be stealing," said Rancho Mirage resident Sharon Peterson.

"Today it's Target and next week its going to be Walmart or Macy's or something like that," said Kipatrick. 

Karen Kaess says she's putting away the plastic.

"I am paying cash I'm not going to use a debit or a credit card, not until I know they've got their problem taken care of," said Kaess.

We talked to the manager at the Target in Palm Desert, while there are no signs inside the store talking about the security breach, he says all staff have been apprised of the situation and are ready to answer customers questions.

"I am worried about it because I don't want my identity stolen.  I can't afford it," said Kipatrick.

Target warns customers to change the pin numbers on debit cards, and check their credit card statements for suspicious activity.

"I called my banks and they assured me that what ever expenses might have been put on there by somebody that was unauthorized would be taken care of by them, but it still doesn't correct the situation," said Kipatrick. 

"That's always been a risk with credit cards, that dates back to the days when you wrote a number on a piece of paper," said Palm Springs resident Howard Johnson.

Estelle Rich has been through this before.  "Same thing, I got notified immediately by the credit card company and within three days I had a new credit card, I think it happened to me three times," said Rich.

She didn't lose any money but says it's a big inconvenience.

"The day it happened, I didn't know about it naturally and I went to another store and I gave my credit card and it was no good," said Rich.

"It's really important to know what ever we spend it has to be checked, every time, because there could always be someone who is getting into your private stuff," said Peterson.

Target also set up a hotline for you to call if you have any questions 866-852-8680.
