1, equipment information
When scanning a QR code, we usually need to open the corresponding applications, such as Alipay and WeChat. These applications need to get our device information, such as device model and operating system version. This information can be collected and stored by applications for user behavior analysis and product service improvement.
2. Geographical location
When we scan the QR code, the application may get our geographic location information. For example, if we use Alipay to scan the QR code for payment, Alipay will obtain our geographic information for security verification and fraud prevention. Applications can store and analyze this information to provide better service and marketing.
3. Personal identification information
If the QR code we scan contains personally identifiable information, such as ID number and name, then this information may be collected and stored by the application. For example, when we scan a QR code and log in to a website, the website needs us to enter personal identification information for verification, which may be collected and stored by the website.
