Can I deduct money from my credit card without a password when booking a hotel?

You can deduct money. The website has an agreement with the bank, and the credit card information can be directly deducted in the background.

When using a credit card, there are some details to pay attention to. First of all, it is best to remember the verification code, or erase it, or hide it with tape. Don't disclose the card number, expiration date, verification code and other information or record it in the computer to prevent it from being stolen by hackers. Secondly, in the absence of protection, it is best not to let the credit card leave your sight to prevent key information from being copied away, such as not letting the waiter swipe the card when checking out at the hotel; Finally, the credit card SMS reminder function is opened.
