Explain to me how QR codes work

577 viewsOtherTechnology

I understand the code itself is a different make up of black/white grids to get your phone to recognize a linked site. But at some point won’t we completely run out of possible image combinations making them obsolete or is it something that regenerates a new site to QR connection? (On mushrooms so I might not have asked this very well lmao)

Basically will we run out of QR codes and if not how is there an endless supply?

So one thing to keep in mind: QR codes are just a way of writing something (such as a url to a website) in a way a computer can easily make sense of it reliably. That is to say, QR codes are not “linked” to anything, they’re just a different way to write. You can use a QR code generator yourself to try it out and note same input always gives same QR code.

Now to answer your question, QR code combinations, that is to say, all the ways we can arrange the black and white squares to make unique messages, depending on standard, amount to more than there are atoms in the universe, so, in theory yes, in practice no.
