关于如何取票

我在网上订了一张从戴高乐机场到AIX EN PROVENCE的火车票，付款后才发现是到车站取票，现在我已收到了确认信，但我不知道到车站取票时需要什么凭据，是不是把确认信打出来拿到售票处就可以了呢？

网上返回的信息说，

Purchase and pay for your ticket on-line now and pick it up at an automatic ticket machine.



You reserve and pay on-line.



You retrieve your ticket from an automatic ticket machine at the last moment, just before your departure.



Note : 3 out of 4 train stations have automatic ticket machines. If this is not the case, please pick up your ticket at the ticket counter.


可是我不知道到自动售票机上如何取票，用什么凭据呢？


谢谢啦！
