Anyone could set up a website and point a QR code at it. The issue is one of longevity - what use is a QR code if the site/domain goes down in 5 years? It has to be something which lasts a period of time into the future guaranteed. Or the QR code is just self-describing - 2kb of information about the person.
As for this service, it looks like BS. I see no evidence on their website that they will even try to hold the server in perpetuity or even guarantee it will be up a year from now. I expect the service to last as long as they can convince people to fork out £200 for a link, but that’s it.
Arweave permaweb linklink2 or data hosted directly on ethereum blockchain. You could also use fountain coding to chain multiple qr codes and encode all the data directly in them. It would probably require some crank operated flip book like contraption behind transparent glass.
As for the service, it doesn’t look very expensive to run, 1 or 2 new clients a year is probably enough to sustain it. I would expect it to run so long as the owner is alive, ironically.
