QR code, or quick response code, is a 2D barcode in the form of a square which contains several smaller black and white squares. It is like a new version of a barcode.
These QR codes are only readable when using a device, such as mobile phones or tablets, and other QR code reading devices.
Usually to use the system, consumers can simply download a reader app from their app store.
Once the code has been scanned, users will be directed to a page with information regarding a service, product, area, etc.
