To prevent credit card deposits from being stolen, the specific operations are as follows:

1. Users should take good care of their credit cards to prevent them from being lost.

2. Users can sign on the back of the card. Most merchants will compare the back signature when the user swipes the card to sign, and will refuse the transaction if the signature is wrong.

3. Users should choose formal channels to apply for cards, and don't enter card numbers and personal information online at will.

4. Turn on the credit card SMS reminder function, and every consumption will be notified by SMS, so that you can find out whether it has been stolen in time.

5. Turn off the secret-free payment function of the credit card, or use the wallet with anti-NFC function to prevent malicious theft.
