Hehe, TIL I can hear NFC through my headphone cable
I had my headphones plugged into the cable from my PC, but was also using my phone when I started hearing a series of clicks and then a short high pitched squeak. Played around with airplane mode and eventually narrowed it down to the NFC. That’s pretty cool!
Now I’m tempted to go chuck some data on an NFC tag and see if I can hear the data 🤔
Probably a bad idea, could end up being super loud or something. Who knows. Anyway I’m bad at resisting bad ideas, will be back later with a status update

I did it! It wasn’t super loud, even on max volume. It’s super cool. Also TIL my NFC tags have a size of ~500 bytes
