These days, the ubiquity of smart mobile devices also provides users sweeping access to QR code-based applications through the cameras in their smart- phones and tablets. These applications span a wide-spectrum of use cases that completely transcend the industrial automation setting for which QR codes were originally developed. With ever increasing computing and communication capabilities and improving camera hardware, smart mobile de- vices are also driving enhancements and improvements to the QR code de- sign. In this thesis, we propose a dual modulation approach to create a novel 2D barcode design that exploits the high spatial resolution of contemporary smart mobile devices.
