What's the difference between fast payment and small secret exemption in JD.COM? COM？

1, secret-free payment refers to direct payment without password, which directly deducts the money from your bank card.

2. Express payment means that users only need to provide information such as bank card number, account name and mobile phone number without opening online banking when purchasing goods. After the bank verifies that the mobile phone number is correct, the third party payment sends the mobile phone dynamic password to the user's mobile phone number, and the user can complete the payment by inputting the correct mobile phone dynamic password.
