The image was built into the sidewalk with the same black and white stones that decorate sidewalks around town with mosaics of waves, fish and abstract images, locals said.
The launch of the new bar code system attracted onlookers, who downloaded an application to their smartphones and tablets and photographed the icon with great awe and expectation.
After scanning, the application read the code and they were then taken to a website that gave them information in Portuguese, Spanish or English, a map of the area and other related information.
They learned, for example, that Arpoador gets big waves, making it a hot spot for surfing and giving the 500-meter beach nearby the name of “Praia do Diabo,” or Devil’s Beach. They could also find out that the rock is called Arpoador because fishermen once harpooned whales off the shore.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.
“If you add the number of Brazilian tourists, this tool has a great potential to be useful,” said Marcos Correa Bento, head of the city’s conservation and public works.
