急问关于网购火车票的那个pdf 收据，晚上就要走

看过以前的帖子，如果选的是Ticketless delivery solution with issuance of payment receipt via e-mail

只要把它发过来的一份pdf文件打印出来就可以了

收到的确认email里也是这样写的：

If you've chosen the Ticketless delivery solution with issuance of payment receipt via e-mail, after boarding the only check made will be that of your presence on board. Please print the payment receipt attached as you will need it to notify your PNR code number to the on-board personnel and to request a bonus voucher if necessary.


意思就是打印出来，而且写的是因为需要notify PNR号码，所以要打印收据带上

可是收据上，我刚才打印的时候才发现，写着这么一行字：

ATTENTION: this payment receipt is not valid as a travel ticket as it relates to a ticketless purchase.

To register your presence on board, please notify the ticket code (PNR) to the train personnel.


我有点看糊涂了。。。

PNR号码到底是个什么东西？是不是就是收据上那个条形码呢？

还是说这段英文写的有问题？

希望知道的朋友能够解答一下，谢谢
