9.Hong Kong
Hong Kong scored quite well in key areas, including the digital governance ranking (3).However, its quality-of-life score(70)dropped the city down to ninth in my ranking of smart cities. Hong Kong is experimenting with RFID technology in its airport, as well as throughout the agriculture supply chain. The city has also been a leader in the use and adoption of smart cards,which are already used by millions of residents for services like public transit, library access,building access,shopping,and car parks.
