Bicycle riders have to pay a monthly subscription to gain access to ECO-Cycle, and they are issued a personal card. Whenever they want to park their bikes, all they have to do is position them in front of one of the above-ground booths and swipe their card through a reader. A mechanical arm clamps it in place, the booth door opens and the bike disappears underground. The whole process takes just 8 seconds, and retrieving the vehicle is just as fast. Ever since the solution was implemented in Konan Hoshi No Koen Park, in 2010, illegally parked bicycles have mostly disappeared from the area.
