  The limited express trains as described above are popular and crowded, so there is a problem that passengers boarding from stations other than the first station can hardly secure a seat. For this reason, passengers have been requested to sit on their seats because the railway companies that operate such express trains may pay a fee.

  On the other hand, in the technique of Patent Document 1 described above, it is necessary to write ticket information such as a free seat green ticket on an IC card. For this reason, there is a problem that it is necessary to change the design of the IC card and the like, and it is necessary to test whether other information written on the IC card is affected by this change. In addition, with respect to IC cards that are increasingly used, there is a problem that it is difficult to change the design (or specifications) of IC cards used for mutual use due to the convenience of a certain railway company. Moreover, in the technique of the above-mentioned Patent Document 1, there is a problem that it is not guaranteed that the seat is reliably secured.
