QR codes can be scanned and decoded by most mobile devices. So, when someone sees a code in an ad, they can simply scan the code with their mobile phone’s camera and/or barcode reader. Once they scan the ad, it can take them to a message, a discount offer, your website, a video, or pretty much wherever you want to take them.
QR codes make it easy for Smartphone users to scan codes to get information about your business rather than having to send a text message, make a call, or wait until they get home to look at your website. This makes your advertising job a whole lot easier as it requires minimum effort on your part to get this accomplished.
