in the notice, the central bank requires card issuers to fully disclose the credit card overdraft interest rate and update it in time through the official website of the institution, and should indicate the credit card overdraft interest rate and interest settlement method in a prominent way in the credit card agreement to ensure that cardholders are fully aware of and confirm their acceptance. When disclosing the credit card overdraft interest rate, the annualized interest rate should be displayed in an obvious way, and not only the daily interest rate and the daily repayment amount.
