抄録

Over four million individuals have already tried the Suica system, introduced by the East Japan Railway Company on November 18,2001,and these customers have responded favorably. During the 14 years that this system was in development, researchers focused on high-speed processing as the critical development theme, especially at automatic fare collection gates. That is because customers must have it pass through the automatic fare collection gates smoothly. In this report, I will focus not only on the technical development but also on field tests performed to evaluate the system under conditions similar to actual operations, development of the IC card and its rewriting capabilities for faster processing, and the use of the Touch & Go format, in which the IC and spends more time in the physical range of communication with reader.
