Why does my postal savings card send authentication SMS before online payment, and then enter the verification code? How can I cancel it?

Hello, if you use the online banking of Postal Savings Bank to make online payment, there are three security authentication methods for personal online banking of China Postal Savings Bank: SMS, SMS+electronic token and SMS +ukey, and you need your mobile phone number to receive the dynamic password of SMS; For Alipay cartoon payment, the Postal Savings Bank will cancel the SMS verification process of Alipay cartoon payment transaction from 2010165438+10.9. At the same time, in order to ensure the safety of your account funds, when your daily cumulative payment exceeds the 200 yuan limit, Alipay will prompt you to pay by installing a digital certificate or entering the Alipay SMS check code, and the Postal Savings Bank will also send you a debit message for free after each transaction is completed; I hope my answer is helpful to you.
