However, at the transfer gates the combined use of two IC cards is not accepted even when they're interoperable; therefore, if you want use different cards such as ICOCA, Suica or TOICA for transfer to the JR Line, or use PiTaPa for Nankai Electric Railway or Kintetsu Railway, you should go out through the normal ticket gate and then go in through the normal ticket gate for the line to which you want to transfer.
ただし、乗り換え改札口では相互利用できるICカードの2枚タッチができないため、JRにはICOCAやSuica、TOICAを、南海や近鉄にはPiTaPaを、と使い分けたい場合は、一旦通常の改札口を出場の上、改めて乗り換え先の通常の改札口から入場しなければならない。
