this is a Dallas Semiconductor ibutton which they have affixed to a ring, they were supposed to be highly durable and potentially purvasive hardware authentication tokens. Par for the course for sun they feature an actual jvm which run applets with can crypographically authentice you. It has many hardware features- a battery, which provides an rtc to prevent backdating authentication fames. They're designed to last ten years on a keychain, they're tamper evident if opened and if you open them anyway a microswitch zeroes out the keys. They also zero out on extreme temperatures and unusual voltage conditions.
The ibuttons are still made though no one ever like made them work as a login token for linux or whatever, so you're more likely to find one being used as a key for a safe or a forklift.

@penny I recently saw a hashtag #WeirdOldTech which this could fit under, maybe.
I'd never heard of a JVM signet ring before. Really cool, but also weird. Thanks for sharing.

@penny my local shop has an iButton based login for staff on the self-service checkouts.

@penny I should setup some eBay searches for this, one of the few rings I actually want.

@penny Interesting. How would you change out the battery on one of these critters without zeroing out the keys?
@grumpydad @penny Buy a new one and provision it, recycle old one. Same as the RSA SecureID authenticators and similar. -

@penny OMG IT'S A DECODER RING but for real!!!!!

@penny oh! I remember reading the announcement for these. Always kind of vaguely wanted one.

@penny one ring to bind them, and in the garbage collector find them
hehehe this is awesome
