TUNE 信用卡付款问题

第一次订TUNE,邮箱已收到订单，但信用卡支付的短信没有收到，算不算成功了呀？

In our effort to enhance the security of credit cards used for payment, credit card Bookings made within 5 days prior to check in will require presentation of the said card. Failure to do so may delay your check in process. We thank you for your kind cooperation and understanding

这段一定要选的，是什么意思呀？

不好意思，E文水平差，怕弄错了，请各位XDJM指教啦！

谢谢！
