Call the customer service of the Agricultural Bank of China to see if they can handle it. Many banks can handle this type of business through telephone banking. The customer service of the Agricultural Bank of China is 95599.

The poster may wish to give it a try , to avoid queuing at the bank. After all, queuing is annoying.

Call 95599 and choose manual service, and then tell them that you want to change your credit card consumption to password verification.

------------------

However, I personally feel that the poster does not need to change this method, after all, if signature is used , the merchant is obliged to check and verify the signature; in addition, if you choose password verification, it will be easier to expose your card password and increase your risk of using the card (remember to keep it confidential when pressing the password to prevent others from prying )
