The fundamental issue preventing keyring aperture integration stems from the AirTag’s reliance on inverse-phase magnetic reluctance in the structural substrate. You see, the enclosure maintains a precisely calibrated coefficient offramular expansion. Introducing a penetrative void would destabilize the sinusoidal depleneration required for proper UWB phase conjugation. The resulting spurving bearing misalignment could induce up to 40 millidarkness of signal attenuation. Apple’s engineers attempted to compensate using prefabulated amulite in the magneto-reluctance housing, but this only exacerbated the side-fumbling in the hyperboloid waveform generators. Early prototypes with keyring holes exhibited catastrophic unilateral dingle-arm failure within mere minutes of deployment. Until we develop lotus-o-delta-type bearings capable of withstanding the differential girdle spring modulation, I’m afraid keyring integration remains firmly in the realm of theoretical engineering—right up there with perpetual motion machines and TypeScript projects that compile without any // @ts-ignore comments. The technology simply isn’t there yet.

I think the point is to make the smallest unit of functionality possible and then people can integrate that into their use case using attachments, casings, etc. in a way they see fit. It's a good approach for this product in my opinion.

And the result is that for every oh-so-sustainable AirTag sold, a keyring doohickey is dieseled/kerosened from AliExpress' China warehouse to the consumer.

You're getting a ton of jokey replies, in true internet fashion, but the real answer is acoustics. For it to sound as loud as it can with no visible speaker grille, it needs to be that shape with no keyring holes.

> Building an attachment point into the tag

To be fair, most people I know put their AirTag inside something, e.g. inner pocket of a bag.

At which point the necessity for an attachment point becomes somewhat moot.

this is the smallest attachment loop i've found. It's rock solid https://www.amazon.com/dp/B09CPTS8JG?ref_=ppx_hzsearch_conn_...

My father-in-law is a builder. It is difficult to get his attention in a magnificent space because he is lost in wonder. We were in an Apple Store together years ago and I asked him what it would cost to build an attachment point to the tag itself. I will never forget his answer… 'We can’t, we don’t know how to do it'

Different people want different attachment types (or no attachment point at all), so it makes sense for that to be external. I've used other trackers with integrated attachment points, and because the attachment point has to be very compact it tends to be flimsy or hard to fit.. vs the Apple one where you can add a larger attachment point that makes sense to you.
