Suppose it is easier if your rolls don't have space to write all that stuff. The buy link is nice, but seems like it's just front loading that work and asking for a stale link.
Otherwise, it's cool.
wdym by that?
You're going through the work of saving the link when you make the QR code. Rather than doing the work when you run out of plastic thread. Hence, the work is front loaded.
Links often go bad, or rot, or go stale. Meaning that a link you make to some Amazon -- or whatever -- page now might not exist in 3 months. So the work might not be worth it.
Still cool.
QR codes don't just hold links. They're probably just putting the information directly in the QR code.
Right, and the links can go stale, so they're a bit superfluous.
I don't think you understand what I'm saying. A QR code can just be plain text, no link at all. The QR codes they're talking about likely are just the raw data.
They literally stated that they included a URL for purchasing the product. It's in the title of the post.
They are using a note app with pre printed qr codes... So they write down the time of unboxing and where they got it in a note app. The buy link might go stale, but the rest of the information stays. Unless the server of the note app goes down.
