One of the hottest new tools at this year’s NAR Trade Show was QR (quick response) codes. These funny little square-shaped boxes filled with squiggly marks may be the next hot thing in real estate or one of the greatest duds ever.
What’s a QR code? According to Mashable, "a quick response (QR) code is a two-dimensional code that can be scanned by smart phone cameras to automatically pull up text, photos, videos, music and URLs. These codes have become mobile-friendly ways to point people in the offline space to online resources."
An even simpler explanation is that a QR code is a barcode in a square box format. QR codes are especially useful for retailers because they provide a way to send coupons to cell phone users. They also communicate other types of information.
