Can also be embedded in digital camouflage or put on helmets. This is the simplest visible version-- hyperspectral imaging permits much more. #Hobbies #Technology Fri, 26 Sep 2025 12:32:16 -0700 phosita from private IP Reply #17443992 👍 It is probably disadvantageous to encode any sensible information in the QR code. Remember this? https://en.wikipedia.org/wiki/German_tank_problem Also some thoughts, in no particular order: (1) suppose you're a grunt manning a weapons system. You see a vehicle with a big ol QR-code-lookin' thing on it, but you can't get a clean read with your code reader doodad. Maybe it's due to smoke, maybe it's due to mud, snow, or gibbets of exploded soldier-flesh, or combat damage, or graffiti, or a durian pizza stuck to it. You think to yourself "hmm, has an imperfect looking QR code and looks sorta nonthreatening I guess, probably one of our'n" and you return to chewing your tobacco. Now suppose you're an enemy who wants to exploit Grunt's heuristic laziness. You false-flag-qr-code your materiel in a way that makes Jimbob 900 SAT infantry think it's friendly: it just has to look like a valid QR code *TO A PERSON* even if it doesn't verify, for long enough for the bearer to gain the initiative. That's a bingo! You just bought yourself a little time, at least. Which could be decisive. (2) if you intend these qr codes to work in other-than-visible light, you have to hack around two more issues: (a) if you hack by making the qr code emit somewhere on the EM spectrum, then you've just self-target-designated your shit to any adversary who can detect that emission; and (b) if you hack by making the qr code (in essence) fluoresce when painted by such-and-such wavelength, then it's just 2(a) with extra steps. (3) Suppose you paint one of these QR codes on a tank. Then suppose Enemy captures your tank, possibly before you know it, fog of war, yadda yadda. How are you going to inform whatever backend system is underneath SPECTRE that a heretofore-valid QR is now actually invalid, in use by enemy, and suddenly a valid target? (4) I'll go even further and posit that, because the US military is primarily a logistics company, there are already pretty robust asset-tracking technologies in place for knowing what widgets are where, the origin of the widgets, the destination of the widgets, etc. Not that whatever these are can/should be used for IFF, mind you. Just observing. (5) QR code stuffs? Line of sight only. Might not have to be YOUR line of sight, but it would have to be at least line of sight with someone who is a friendly with respect to you. Put otherwise, how you gonna see around corners or over terrain? (6) IFF is definitely A Thing with aircraft, capital assets operating in kind of a simpler environment than down in the blood and mud on the ground. I guess I could maybe see the point of equipping a big-ticket item like a tank with an IFF to prevent it shooting another friendly tank. (7) The solution to infantry-on-infantry fratricide is just to keep college unaffordable and ensure a sufficient flux of underclass into the cannons' food troughs. Thanks for coming to my TED talk.
