When booking air tickets and hotels, it is often necessary to provide whether the credit card number is safe.

I am an insider and have worked in various online travel companies for a long time, such as e-Dragon, Golden Century, and online game world. I'll tell you why you want a credit card number! In fact, it is not these companies that want your card number, but the hotel. The main reason is that I am afraid that the guests will not come, that is, I will not stay if I book it! If you provide the card number, even if you don't live, you will be deducted from the corresponding room rate! As for safety, it is definitely safe, because the hotel will not cross your account unless you don't check in! These companies have no right to do so, because banks will not give such companies the authorization to transfer money! To be honest, when I worked in these companies, quite a few guests did not check in after booking, which would affect the cooperative relationship between the company and the hotel. If they don't go after booking, it will affect the reputation of the company in the hotel! In the future, when the room reservation is tight, it is difficult to book a room from the hotel. At that time, guests can't book rooms through these companies, so they need your card number as a guarantee!
