QR Codes Embedded into Sidewalk to provide tourist information.
Rio De Janeiro has embedded QR codes into their sidewalks to help tourists learn more about the city and more easily get to where they are going. The codes have been embedded into the city’s traditional mosaic sidewalks in the form of black and white tiles. When the tiles are scanned with a smartphone, a local map and information is provided to the user in English, Spanish, or Portuguese. Brazil plans to embed roughly 30 QR codes at beaches, vistas and various historic sites around the city, helping Rio’s two million foreign visitors each year get around.
