Silly question: damage to NFC tags via electrostatic discharge?
-
Can the NFC tags in the ring get damaged by electrostatic discharge?
Was just walking down the hallway of the office today and reached for my office door handle - ZAP. I'm not one to drag my feet when I walk, so it wasn't a huge static shock, but I can imagine that with the right factors you could recharge a couple of Eneloops with enough of a jolt.
Nothing happened to the tags in my ring, but I was wondering in general if the NFC tags could be damaged by a strong enough ESD? I don't think titanium conducts electricity like copper does, but could it carry enough that the NFC tags could fry themselves? Or are these NTAG203's the newer ones from NXP that are safe from ESD?

Hi mate, the bare NTAG203 chips are rated at 2kv for ESD. I'd expect the ring to be considerably better!
-
the tags inside the ring should still be surrounded with plastic so there shouldn't be a way to make contact to the titanium.

We designed and tested the rings to take a lot of ESD beating, it's likely your skin will be damaged prior to the ring.
I lost my actual test results for this but it was basically a case of using one of those static generators and zapping it at different voltages.
The electronics of the ring are never exposed to titanium and our absorber layer acts as an insulator.
Basically you should be fine from ESD.
I'd be happy if someone wants to run some tests to see what environments of ESD the ring can tolerate, 5 free visual fail rings to whoever gets the best/most enlightening/well documented results :P

Do wool socks and carpet count as a proper test environment? ;)
