Are you using QR (Quick Response) codes as part of your marketing? QR codes are an efficient way to give your customers instant access to unlimited information about your listings or your business. The custom-made readable bar codes store alphanumeric data that is read by a QR scanner app on a smart device. The user simply scans the QR code and — depending on how it is set up — is either directed to where you want them to go (URL), or receives the message or contact information you want them to have, such as email, SMS, text or contact information. For example, if you create a QR code that directs readers to your website, then scanning the code will instantly take them to that site.

We’ve all seen real estate signs that include a QR code, but what are some other uses for them? Perhaps you’d like to make it easy for potential buyers to find a specific property. Simply include a QR code on the bottom of the property flyer that is set to automatically send the reader text and map directions. Have a vacant property? Consider adding a QR code to the lock box that links to the property’s webpage. This will give curious visitors a chance to see and learn more about the house than just peeking through the windows. The possibilities really are endless.
