To use QR codes conveniently you must have a mobile device equipped with a camera and a QR code reader application. Newer smart phones often have this app pre-installed; if your device does not, visit your app store and download a QR code scanner app to get started.
To scan the QR code, get out your phone and open the app, steady your hand and center the code on the screen. When your device has completed scanning, you will be automatically redirected to the webpage, and information, held within each unique QR code.
Based on your current location, you can also view the map to locate other nearby points of interest. There are no fixed routes – instead, you can explore sections of the city at your own pace, based on your own interests.
