If you can't set up credit card security, you can call the credit card center.

Ask them to set a credit card limit of 5000 yuan (or set it smaller, such as 1 yuan) and you must enter a password.

In this way, when you pay a large sum of money, you can call the credit card center to close this restriction.

Call again after the payment is completed, and ask to open this restriction.

That's it. I hope I can help you.

Please consult the bank credit card center for details. They are more professional.
