That's not really how qr codes work. They can only see you scanned it if it's a url or something and you click on it.
Also qr and other data matrix codes are quite redundant and can be read with something like 40% missing, depending on how it was created.
Ya I'm aware of how qr codes work. It'll definitely be a url. Like most qr codes most people scan. Go to a restaurant scan open a link to a menu. They'll do that.
And you're right they are redundant. Great for still being scannable if a bits worn off a table or a box in a warehouse. But silly to suggest somehow a pig couldn't damage or cover 40% of a small square. Unless the code like covers they're whole back... Which would be funny looking.
