Do you have Octopus Card for your daily use? I believe that 95% above of Hong Kong people whatever the person is a CEO or a blue-collared worker must have Octopus Card in their wallet. At the first beginning Octopus Cards was only used in transportation; it now has been widely spread to many different fields such as car parks fast food chains convenience stores supermarkets etc. Owing to the convenience of the Octopus Card and its irreplaceable functions it will probably develop into one person one card.
