But for me, I don’t want to expect just the website if I’m taking the time to scan the code. If I have their materials, I could open my browser and visit their site at home.A QR code should attract me more than just your blog or website. It should give me something useful “on the go”. I’m not scanning it and read the whole website on my phone. We should remember that we are still using our phone and most likely we are at this time not close to our Mac/PC/Tablet.
For me, I give QR codes a few seconds to attract or inform me. This decides if I’m leaving or staying. I’m asking myself, what does the QR code want to tell me which I don’t already know from the materials?
For redirecting just to the website, it’s wasting my time. If they are using a vcard to the sales or consulting person, I would benefit from it as I don’t have to create a new contact.
So, just speaking for me, if you use a QR code, give me something different.It is necessary to inform the user what to expect when scanning the QR code. If I know that I’m able to find handy links to your social media profiles along with some information – it would be more attracting. As said, it depends on the mission and the “material” the QR code should reflect.
And you are absolutely correct: “Use the prospects time with value. ”
