紧急！在法铁官网定火车票用工行信用卡，显示

http://en.voyages-sncf.com/en/


在法铁网站订火车票，用的是工行多币种卡，开始没有开通3D secure功能，打电话给工行说在网上银行设置下外卡组织验证服务就行，于是设置开通，再次 预定，但两次到这步就没有下文了，页面显示：
This payment will be authenticated by 3D Secure. Your bank with authenticate the payment request before authorising the payment.If you have any questions about the process, please contact your bank.You can also choose another payment or retrieval method by clicking on "Change my order" on the payment page.
这个算是啥意思？一般正常应该是怎样的情况？
会不会授权通过以后一下次两笔付款都通过了呢？现在都不敢再定了


谢谢各位先！！
