Bar code mosaics on Brazilian sidewalks offer tourists local sightseeing infomation

Rio de Janeiro is mixing technology with tradition to provide tourists information about the city by embedding bar codes into the black and white mosaic sidewalks that are a symbol of the city. The city plans to install 30 of these QR codes at beaches, vistas, and historic sites, so Rio's approximately 2 million foreign visitors can learn about the city as they walk around.
