Is it just me or is the concept of QR codes fundamentally flawed and ripe for abuse? Basically any QR code that exists can be overwritten by a simple sticker of another QR code. How do you prevent this?

- mbesto 13y agoBut those all have specific use cases. QR codes on the other hand are meant to be universal. Imagine the QR codes in a museum all replaced with links to porn sites (two different uses - one is for information and another is for advertising).
- DrewAllyn 13y agoFor QR codes generated on the fly on another screen, that is obviously impossible. For QR codes on posters, I think the effort required to actually go about making stickers far outweighs any potential gain from hijacking a QR code.
- mbesto 13y agoHave you ever seen how many stickers for .com's still exist on post signs today? Imagine for every QR code for a movie poster someone slaps a link to their band's website. This would scale a lot better than their band's name with the .com, it would be cheaper to make, just as costly to distribute, less obtrusive, create more attention, and be way more deceptive.
- leoedin 13y agoFundamentally at some point there has to be some trust. Equally you could slap your own RFID tag over someone elses (perhaps inducing a high enough voltage to kill theirs first). We already have issues with bank card scanners placed on ATMs. I don't think we've really solved the problem beyond user awareness and frequent monitoring.
