HOUSTON (KTRK) -- You've probably seen them and maybe even scanned a few by now. QR codes are popping up on product labels, magazine ads, even gas pumps. You scan them to get more information. But scanner beware.
Jorge Ezeta thinks QR codes are incredibly convenient. He likes scanning them for more information on a product he might want to buy.
He said, "It really helps you make a shopping decision."
While that is helpful, you can't really tell what information is stored inside that code until after you have scanned it. And that can be bad, according to malware researcher Tim Armstrong with Kaspersky Labs.
"There's a danger inherent in using these types of systems," he said. "They can link to malicious websites or phishing pages just as easily as they can link to legitimate information."ABCnews
