COLLIER COUNTY, Fla.- "I think we're a society that really likes convenience, I know that I don't carry cash on me either."

But Detective Cara Melito believes you shouldn't be scared.

"I think overall it is very safe," she said.

In a new development, the Department of Homeland Security is now warning retailers about a widespread virus, likely from overseas, that could hijack credit card readers in stores. Between the data breaches at Target and Neiman Marcus, nearly 110 million people may have had their personal information stolen.

"I don't think it's going to go away, I think it's likely that there will be another type of network intrusion like that."

Some banks are now reissuing new cards to customers. The Consumer Bankers Association tells WINK News it's costing financial institutions millions of dollars to clean up Target's mess.

"It looks huge because it involves so many card holders but basically it appears that it, I would think, that the attack was specific. It's just a target, no pun intended, target rich environment, of all of this information thats gotten at once as opposed to little by little stealing batches of information more slowly," said Detective Melito.

If you continued to use your debit and credit cards, Detective Melito said it's important to get into the habit of checking your statements everyday. If you do that online, make sure you have a strong password with letters, numbers, and characters.

So far, Chase, Citi, Suntrust, and Fifth Third Bank are issuing new cards to most customers. Wells Fargo and Bank of America are monitoring the situation and giving out cards only to customers who may be at risk.
