Is the simple passive NFC functionality even handled the same way as the much more complex AirTag functionality? With this NFC URL modification, does the regular AirTag functionality even still work? I love seeing things hacked like this, but for all we know this same thing could have been accomplished by swapping out the guts of the device. (Note: I'm not saying the demo is a fraud, I know stacksmashing is legit) There aren't many details in the article, and the demo doesn't really show much.
