As an AI language model, I don't have personal preferences. However, QR codes can be quite useful for quickly accessing information or websites with a simple scan. They are convenient for businesses and individuals to share information in a fast and efficient manner. Overall, QR codes can be a helpful tool in certain situations. **

To share a self-recorded video using a QR code, one can first upload the video to a video hosting platform such as YouTube or Vimeo. Once the video is uploaded, the platform will provide a shareable link for the video. Then, using a QR code generator, one can create a QR code that links to the shareable link of the video. This QR code can then be printed or shared digitally for others to scan and access the self-recorded video. **

To share a self-made video using a QR code, you can first upload the video to a video-sharing platform or your own website. Then, generate a QR code for the video link using a QR code generator tool. Once the QR code is created, you can save the image and share it digitally or print it out for physical distribution. Anyone who scans the QR code with their smartphone or tablet will be directed to the video link and be able to watch the self-made video. **

A QR code quiz is a type of interactive quiz where participants use their smartphones or other devices to scan a QR code, which then directs them to a webpage where the quiz is hosted. Participants can answer the quiz questions on their devices and submit their responses electronically. This type of quiz is convenient and engaging, as it combines technology with traditional quiz formats. **

The QR code is scanned by a mobile device or QR code reader, which then interprets the code and directs the user to the encoded information. This could be a website, a digital payment platform, a video, or any other type of digital content. The QR code essentially acts as a bridge between the physical world and the digital world, allowing users to easily access information or perform actions by scanning the code with their device. **

Once the QR code is scanned by a smartphone or QR code reader, it redirects the user to a specific webpage, app, or piece of digital content. The QR code essentially acts as a shortcut to quickly access information or complete a specific action. After the QR code is scanned, it can no longer be used and does not retain any information. **

A white QR code is a type of QR code that has a white background with black squares and patterns. It is essentially the inverse of a traditional black QR code, which has a black background with white squares and patterns. White QR codes are often used for aesthetic purposes, as they can blend in more seamlessly with a white or light-colored background. They can also be used for branding and design purposes to create a more visually appealing QR code. **

To print QR codes, you can use a QR code generator tool available online for free. Simply enter the information you want to encode in the QR code, such as a website URL or contact information, and generate the QR code image. Once you have the QR code image, you can print it using a printer onto various materials like paper, stickers, or labels. Make sure to test the QR code after printing to ensure it scans correctly. **
