Why does WeChat scan code fade out the confirmation of mobile phone number information?

Privacy protection, static code analysis mode restriction, need authorization.

1. Privacy protection: WeChat attaches great importance to users' privacy. In order to protect users' personal information, some numbers will be blurred or hidden when displaying mobile phone number information to prevent users from stealing personal privacy.

2. Limitations of code scanning methods: Some code scanning methods cannot directly obtain mobile phone number information. For example, the QR code only contains the user's WeChat ID, but does not contain specific mobile phone number information.

3. Authorization required: In some scenarios, user authorization is required to scan the code to display specific mobile phone number information. For example, when users need to use a service or buy goods, they need to scan the code to confirm the mobile phone number and agree to the relevant terms.
