Sidewalk QR Codes

Sidewalk Bar Codes to Educate Tourists Technology is meeting tradition in the Brazilian city of Rio de Janeiro, where two-dimensional bar codes—or, to be more precise, QR codes—are being embedded in the black-and-white mosaic sidewalks that are hallmarks of the city. By downloading an app to their smartphones or tablets and photographing the QR codes, tourists can go to a website that will provide them with information about the city in Portuguese, Spanish, or English. The city plans to install the QR codes in such popular locales as beaches and historic sites so that the 2 million foreign tourists who visit Rio de Janeiro each year can easily learn about the city as they walk its picturesque streets.
