Will paying with WeChat change send a message to the mobile phone bound to the bank card?

The reason for this is the following：

Wechat payment:

Wechat payment is based on Tencent's own back-office financial management system for online transactions, such as Tencent Tenpay.

The amount data of WeChat change is stored in WeChat's own background, and there is no intersection with the bound bank card and banking system. Therefore, when a transaction occurs, only WeChat is used to change the zero balance, and no bank card is involved, so there will be no SMS reminder.

However, after WeChat payment, there will be a message reminder on the official account of WeChat Pay.

Bank card transaction:

Bank card transaction is the bank's own system, and SMS reminder will take effect only if the bank opens SMS reminder function. For example, WeChat cash withdrawal and WeChat change recharge all use bank cards, so there are SMS reminders.

Wechat changes the viewing mode:
