You may have scanned a QR code.  But do you know much about them?

The 'QR' stands for 'Quick Response' and the funky black-and-white square works as a hyperlink.  It takes you and your smart phone from a magazine or street sign to a webpage.

"A worst-case scenario would be you install a piece of software that does a variety of things," said David Gewirtz, Security Editor for ZDNet. "One, anything you send as an email, or type into your phone is then transmitted to the hacker."

QR codes have become a go-to gadget for marketing.  About 75 percent of retailers now offer the technology.

As a result, companies are setting up secure data centers to prevent hackers from manipulating them. 

A good rule of thumb: only scan codes from reliable sources.

"If you see a random sticker on the side of a street, don't scan it.  If you see something on a random door don't just scan it," said Gewirtz.

There have been no reported cases of QR code attacks yet, according to the U.S. government.
