紧急求助booking预定问题

大家好，我在Booking预定了BEST WESTERN PREMIER FAUBOURG 88 这家法国酒店，预定的时候也填写了信用卡信息，银行提示扣款成功。但是刚才收到邮件
Following the Booking conditions, the total amount of your stay has been charged on the credit card provided.

However, regarding the important amount of this charge and to always better fight against credit card frauds, we need you to send us the following documents:

- A copy front/back of the credit card used
- A copy front/back of its holder’s ID or passport
- The document attached completed and signed by the holder of the credit card
We are waiting for your reply in the next 72 hours in order to confirm your Booking.
主要问题是，他为什么要我们信用卡还有护照正反面信息啊？我感觉这样对我不安全啊？请问这种情况正常吗？
