Many Americans are checking their bank accounts after a security breach was reported at Minneapolis-based Target Corporation.
Target said they had about 40 million pieces of credit and debit card account information stolen between Nov. 27 and as late as Dec. 15.
Target hasn't released how the thieves may have gained access to the accounts.
Financial advisers at Liberty First Credit Union, however, offered up tips for anyone who may be concerned that their information is compromised.
"You shouldn't wait for something like this to happen," Angie Schreiner, the senior vice president of Liberty First's marketing department, said, "especially when you don't know how it happened or where."
Schreiner said the most important thing to do is check your bank account and credit card statements every day.
If you see something that you don't understand, or didn't approve, contact your financial institution right away.
Getting your card cancelled, or a new one sent to you, is often a possibility.
"40 million is a large number to get hit," Schreiner said, "but when you're taking large retailers like target, it does happen."
Schreiner also recommended checking your credit reporter, especially in a few months.
E-mail statements and mobile banking apps can also help you stay on top of your personal information, Schreiner said.
Customers all over the nation were victimized, but online customers apparently have not been affected by the breach. Target has 1,797 stores in the U.S. and 124 in Canada.
Customers who suspect unauthorized activity should contact Target at: 866-852-8680.
