NFC Energy-Harvesting PCB Business Card with an Ethernet patch cable

And how can we tell for sure if it's a good idea too - keep the airwaves clean. Re: the slight wobble, you should be able to order cheap ones in packs of 5 or 10, with custom led colors/locations/sizes/brightness, fitting into a printed card... For future PCB business card ideas: it would be very sped-up, but maybe it would increase "immersion" nevertheless. Every individual product is "easy", but the moment you want two ecosystems to talk to each other. Still, a seriously neat piece of engineering! It's getting insane, I have a usb-c port and a usb-c cable at all times.

Ok is there a version for usb-c? Because that would be 10x or more faster and I have to re-auth all the time. There should be an API to pull this data down. Okay, I really like this, but apparently modern Gigabit ethernet adapters are able to detect this situation automatically?

Terrific presentation. But I have a usb-c port and a usb-c cable at all times.
