And yet, the pathways are littered with QR codes.
They were put there by a group of ten Bolivian teenage girls who wanted to make the hours-long walk to school a little more fun for local children.
The game works by encouraging bypassers to scan the barcodes with their smartphones – the one common technology in the area.
The offline app then presents them with a multiple-choice quiz on a range of educational subjects, such as computer programming, history, English and Aymara — the village's native language. For every correct answer, players receive a point, which they can use to compete against their friends.
For the girls who built the app – "Learn by Sarana" (Sarana translates to walking in Aymaran) – it was their first real opportunity to learn about technology, let alone programming.
