How does Alipay close the credit card for fast payment?

My Alipay has previously opened a credit card for fast payment. When I purchase something on Taobao, I can pay by credit card on the direct payment. This quick payment is very convenient, but I am worried about security. In case my account is stolen, can someone else use my money casually? So I want to close this fast payment, how can I close Alipay's fast payment?

A: First login to Alipay, click [Account Management] & mdash; & mdash; [Account Asset] & mdash; & mdash; [Bank Card], find the bank that needs to be revoked, click [Close];

2, select Close quick reasons to pay and click [Next];

3, click delete to revoke a credit card payment functionality quickly.
