Is there a similar ring with NFC? I have no use for the smart health thingies, which really look like a data driven health gimmicks to me. NFC on the other hand I could find hundreds of applications, from payment to access and transport cards.
I think you're onto something. I would be ok with a watch too.

I've also seen some rings on Aliexpress that purport to support the same capabilites, but havent personally tried them out yet.
I couldn’t find it on the product page: any idea if this has a vibrating alarm? I’m in the market for something to wake me up without disturbing my partner
Wouldn't a watch do that? Ex. the https://pine64.com/product/pinetime-smartwatch-sealed/ is dirt cheap and its alarms just vibrate the watch.

From the little bit of research I just did before buying one, most people are reporting that compared to their more expensive trackers, the heart rate, accelerometer, and sleep tracking functionality are all pretty accurate (good sleep tracking being dependent on a high sampling rate, which decreases battery life), but the blood oxygen and "stress" reporting is uselessly inaccurate.
That has also been my experience with this model. I’ve been using it for about a month now. I originally planned on trying to use the accelerometer data over Bluetooth to build a custom control input for Frame smart glasses, but I got busy and never got around to that. But I’ve been wearing it as a health tracker and the heart rate and sleep tracking seem pretty accurate relative to my Apple Watch, and the blood oxyg…

Yes. I have the Z1 Ring. Getting secure tokens (like payment, door unlock, etc) is possible but can be complicated. The ring is a small target, so not always easy to find the received if you're using it with a phone. Oh, and the software is low level and finickity. I managed to accidentally set mine to read only mode permanently. Review at https://shkspr.mobi/blog/2024/02/giving-the-finger-to-mfa-a-...
The NFC tag is a small target, probably because of the size of the antenna, but the RFID one has pretty good range. I got five of those rings, very much recommended if you have stuff to auth to.

The problem with that idea is that all secure implementations of RFID lock the user out, meaning you can't just buy an NFC ring/fob/implant and copy your bank card or transit card onto it. The only implementations where the user can do that are terribly insecure and, while still commonly used, are slowly getting phased out. So for anything other than systems you control or are good friends with the IT guy for, you're…
Right I agree with you on theory. But in practice, I already do clone most of my smart cards on small NFC stickers on the back of my phone case. The things is 99.9% of access cards (where I leave at least) are default-encrypted mifare classic, making cloning trivial. Transport cards are an other beast since they have their own backlog and proper encryption, but there are ways. So all in all, dumping the card is not t…

Dangerous Things (popular RFID/NFC implant makers) sell dual 125khz+13.56mhz clonable rings, but they're way overpriced ($130). I bought my "V1" back when they were still $60, and FWIW, if you know what you're doing, it does work. I've also seen some rings on Aliexpress that purport to support the same capabilites, but havent personally tried them out yet.
How accurate can the data of such a smart ring be or do other smart ring have so high margins?
