There are several ways to scan a QR code, depending on the device you are using:

1. Smartphones: Most modern smartphones come with a built-in QR code scanner. Simply open the camera app and point it at the QR code. The code should automatically be scanned and the information contained within it should be displayed on your screen.
2. QR code readers: You can download a QR code reader app from the App Store or Google Play. Open the app and point the device's camera at the QR code. The information contained within the code will be displayed on the screen.
3. Desktop computers: Some web browsers, such as Chrome and Firefox, now have a built-in QR code scanner. Simply right-click on an image of a QR code, and select "Scan QR code." This will open the URL contained within the code in your browser.
4. QR code scanners: you can use a QR code scanner device to scan the QR code, which will show the information contained within it.

If your QR code is not working, here are a few steps you can take to troubleshoot:

1. Check the link or data: Ensure that the URL or information embedded in the QR code is correct. If it's a broken link, incorrect URL, or incomplete data, the code won't function.
2. Scan with a different device/app: Some QR code readers may have trouble with certain formats. Try scanning the code using a different app or device to rule out compatibility issues.
3. Test your internet connection: If your QR code links to a website, make sure you have a stable internet connection when scanning.
4. Ensure clear contrast and resolution: QR codes need to be high-resolution and have clear contrast between the code and the background (e.g., black code on a white background). Blurry, distorted, or low-contrast codes may not be scannable.
5. Check the size of the QR code The code should be large enough to scan easily. If it's too small, some devices may not be able to read it.
6. Avoid overcomplicated designs: If your QR code is heavily customized (e.g., with logos or colors), make sure the code is still functional and not too distorted.
7. Try regenerating the QR code: If none of the above works, try generating a new QR code and scanning it again.

By going through these steps, you should be able to identify and resolve the issue with your QR code.

Yes, once generated, the QR code is a static image that can be used as long as needed. If the linked content changes (for example, if the URL redirects to a different page), a new QR code would need to be generated.
