意铁订票的问题

哎，终于还是遇到了信用卡deny的问题


我本人的一张招行Mastercard，输入后需要一个securetycode,输入后被deny

我老婆的一张交行Visacard，输入后同样需要一个什么code，但是我们不知道，放弃。过几分钟又拿这张卡试了一次，不需要署号码了，但直接被 deny

同事一张平安的Mastercard和招行Visacard，输入后都出现以下文字

Dear customer,

due to security reasons it is not possible to proceed with the payment: the payment circuit has inibited the transition.


To check the transition inibition reasons, independent fron Trenitalia, we invite you to contact the credit card company/provider or resubmit the purchase, if possible, with a different credit card.


We further inform you that, for departures later than 24 hours, you can alternatively use the Postoclick service, that allows you to make your reservation on line, and subsequently at one of the qualified points (consult the service conditions on the Trenitalia web site)


不太明白意思，是说线路有问题？到底什么卡能付呢？


PS.我用公司的苹果电脑付的，会是这个原因被deny吗？
