I use an IC card when I take trains around Kansai. But there is a problem at one of the stations: About half of the ticket gates at the entrance are IC card compliant. We can also use former tickets and cards. When a train arrives at the station, people who use IC cards rush to the gates. Then sometimes people going into the platform with IC cards have to wait. , wishing even one of the IC-card-compliant gates were entrance only.
