The way I see it, having only a physical portfolio can be inconvenient. You can try this: upload your design pics to a cloud server (like Google Drive or Dropbox) and get a shareable link.

The next step would be to turn that link into a QR Code. It's super easy, and you can find free QR Code generators online or look up how to make a QR code. (Please check the reviews because some QR codes expire quite quickly.) Then, just print it and give it to your clients. All they need to do is scan the code with their phone, and voilà! They can instantly check out your designs.

This way, you can impress them without lugging around a heavy portfolio all the time, and it's great for unexpected opportunities to show your work. It also makes you look up to date with the latest trends and technology, in my opinion.

Thanks, I will definitely try that way! Seems to make sense.
