These codes contain information encoded in a matrix barcode, which can lead to websites, contact information, app downloads, and much more. Essentially, it acts as a digital translator, converting the visual information into actionable data.

- Additional Features: Many apps offer extra functionality beyond basic scanning, such as creating your own QR codes, batch scanning, and integration with other apps.
- Security and Privacy: Choose an app from a reputable developer with a strong privacy policy. Avoid apps with excessive permissions.
- Offline Functionality: Some apps can scan QR codes even without an internet connection, which can be useful in areas with poor connectivity.
