In the photo above, you see the qr code for one of my websites. I had taken a photo of the qr code that’s on the back of one of my business cards. I took the photo using one of my mobile / cell phones. This is just one example of a digital photo of my qr codes. I have taken photos of downloaded qr codes too.
Instead of using business cards, I will start asking potential clients if they can scan qr codes using their phone. If they have this feature on their phone, it saves the environment as they can just scan the qr code in order to find out what my web address is. I will still use the existing business cards too as a backup method.
