Brazil: Barcodes on Rio’s sidewalks

BRAZIL: BAR CODES ON SIDEWALKS GIVE TOURIST INFO

The first two-dimensional bar codes, or QR codes, as they’re known, were installed Friday at Arpoador, a massive boulder that rises at the end of Ipanema beach. 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.

This is in preparation for the World Cup and the Olympics.
