QR Genius - Scanner 4+

A QR scanner and generator app is a mobile application designed to scan and generate QR (Quick Response) codes. Here's a breakdown of its key features and functionalities:

1. **QR Code Scanner**: The app allows users to scan QR codes using their device's camera. When users point their camera at a QR code, the app decodes the information embedded in the QR code and performs the corresponding action, such as opening a website, displaying text, or initiating a payment.

2. **QR Code Generator**: Users can create their own QR codes by inputting text, URLs, contact information, or other types of data. The app then generates a QR code containing the provided information, which users can save or share with others.

3. **History**: The app may keep a history of scanned QR codes, allowing users to easily access previously scanned codes for reference or re-use.

4. **Customization**: Users may have options to customize the appearance of generated QR codes, such as choosing colors, adding logos, or selecting different styles.

5. **Offline Support**: Some QR scanner and generator apps offer offline functionality, allowing users to generate and scan QR codes even when they're not connected to the internet.

6. **Security**: The app may include security features to ensure the safety of scanned QR codes and prevent malicious activities, such as scanning harmful codes or accessing sensitive information.

7. **Sharing Options**: Users can share scanned QR codes or generated QR codes with others via various methods, such as messaging apps, email, or social media platforms.

8. **Compatibility**: The app should be compatible with a wide range of devices and operating systems, ensuring accessibility for users regardless of their device preferences.

Overall, a QR scanner and generator app provides a convenient way for users to interact with QR codes, enabling quick access to information and facilitating seamless communication in various contexts.
