Semacodes are a form of Data Matrix (a type of barcode) resembling a crossword puzzle. By encoding a website's URL they can be quickly captured with a mobile phone's camera and the site accessed via the phone's web browser.
The Semacode can be used on posters, in conference programmes, as the final slide in a power point presentation, on garments - list your uses below.
