Also, the magnetic poles are about to flip any minute now. Not a good investment

In THEORY this is software based enough that they could just push an update, I’d assume/hope… but yeah, could get a bit weird otherwise hahahaa

I don’t get it. What even is the point of the SIID in this situation?
Christ, one of these days I’m going to need to design a passively powered compass implant so cyborgnest can stop sucking at it.

If you do, I’ll need one. I’d MUCH rather an implant than a weird arm band… thing… with very vague feature set… but I’m sure interesting how this pans out since it’s at least SOMETHING in the direction of a new sense…

Its supposed to give you the notification flashy light and there armband has haptic. Absolutely no reason to use a siid.

The parent site boast biometric monitoring

Not with the siid alone there isn’t, now the chip inside is afaik an ntag i2c plus which give a i2c bus that you could attach sensors to which would be cool.
But as of yet to see something that works, I mean temperature is cool and all but blood pressure or o2sat would be better

Notice there overuse of the word platform and enabling -_- they talk about all the vital monitoring but they use sneaky marketing bs to oversell the current offering 
as @Devilclarke said its a chip that a sensor could be added too and potentially code to interact with it but I don’t think they have any info on actual implementations, the site looks like its targeting partners who want to build implantable sensors not consumers since they don’t link to things like impli or the xSIID.

I would agree. Still junky.

It is an NTAG I2C Plus. They’re only using it for the energy harvesting though. They are marketing the SIID module as a sensor platform which anyone can set up their own biometric system on, but it will never work for direct communication between a phone and a sensor. I’m pretty confident they didn’t know how it worked when they made it.
I use the same chip on my business cards. While it does work really well for energy harvesting, it can only act as a bridge between the NFC on a phone and a microcontroller over I2C. The microcontroller acts as the master which communicates with the I2C sensor and relays that information over NFC to the phone. It can’t provide a direct communication channel between an NFC phone and an I2C sensor, and not many MCUs can fit in glass.

Having a sense of the magnetic north would be nice, just because an extra sense would be nice, for its own sake. But it’s hardly useful, apart perhaps for orienteering - and that usually requires more precision, and laying the compass on a map anyway. Unless someone wants to do augmented dead-reckoning

Thanks Satur you basically said exactly what I though. One thing I didnt know was that the chip dosnt act as a i2c master thats a bit shit.

Depending on the precision needed it might be useful for scuba diving assuming it worked underwater.

Just go to a pool and stay out of the oceans. 
In my experience scuba diving in a pool is boring af

Shark free though, and those stupid lil blue octopi that can kill you are in the ocean. Nope.

The blue ringed octopus lives in rock pools, not in the open ocean. Sharks are adorable, pools kill more people than sharks 
. Also surfing in a pool is even more boring than scuba in a pool.
And anyway your not safe on land either:

I agree. They are supposed to stay in the rock pools, I don’t trust those shifty looking fellows. They are smart
Fixed it for you. But seriously though, they look cool, they can just eat me too, which I don’t care for.
Don’t worry, my risk are pretty low as I dislike pools too really.
I would be more inclined to try these if they were available close to me in a pool. But my ears are bad, I can’t even swim 8 feet under without my ears hurting.

I would not be afraid of this. I would ride it into battle. After I put a laser on it.
