What does the mobile phone Alipay short message payment mean?

Alipay SMS payment is a convenient payment service provided by Alipay for users. After the user chooses "SMS Payment" when paying on Alipay or Taobao website, Alipay will send a short message to the mobile phone number bound to your Alipay account. If the balance of the user's Alipay account or the bound bank card is sufficient, just reply to the corresponding confirmation code according to the content of the short message to complete the payment.

Note: If there are more than one smart card or American Express card, it will be deducted randomly until the deduction is successful or the balance of all bank cards is insufficient.

In order to ensure the security of user accounts, SMS payment is up to 2000 yuan per day.
