Sign QR Code We include a QR code on the majority of our signs for immediate access of the in-depth property brochure. What are QR Codes? QR is short for Quick Response (they can be read quickly by a cell phone). They are used to take a piece of information from a transitory media and put it into your cell phone. They have been described as paper-based hyperlinks. You simply take a picture of a QR code with your smart phone, and you get redirected to a website or PDF using your cell phone’s browser. Once scanned, the user will be able to download, save, and send property information within minutes of arriving to the property.
