If just one QR code out of a hundred is bad, that means you have a one percent shot at running into a malicious one. Security is all about checking everything in a group, since you never know which ones might be sketchy. Like, here in Berlin, if you show up to a concert with a bag, some guy is going to look through it. Even if hardly any bags have anything they shouldn't, they still have to check every single one. I really don't have any hands-on experience with QR codes, and I barely know how they work, but I figure they just hold URIs that get opened up. That would make them active content. Letting stuff run without the user doing anything is risky, kind of like letting macros go off in a doc file as soon as you open it. Imagine if every time you downloaded an exe, it just ran right away. That would be a nightmare! So, if that's actually how QR codes work, that needs to be fixed. When you scan a QR, it should just show you the text and let you copy it if you want. If you decide to open it as a URI, that should be your call.
