Tech-savvy travelers hit the road to convenience

Technology is making life easier for travelers in China, the country with the highest number of smartphone users.

Thanks to artificial intelligence, instead of using paper tickets, tourists in Shanghai can now have their faces scanned to hop on and off sightseeing buses.

The first batch of smart double-decker buses supported by Baidu Brain, the AI platform of technology giant Baidu, took to the city's streets in December, according to local media portal Shanghai Observer.
