    one of these popped up for $25 and I've been wanting one for years so I had to do it

    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 have seen these used to authenticate staff at a POS kiosk, especially in bars and restaurants.

        @penny iButtons are still made, but they're just a 1-wire EEPROM with an occasional temperature sensor, the cool JAVA iButtons are not made anymore I think.

        I got so many free samples from Dallas, but I never managed to get a java one.

          @penny Sadly it contains a battery. So the usefulness is limited to its flash.

                    @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.

                        @f4grx @penny Do you know what it loses if it runs flat? Was there an RTC?
                        I have one and never used it because it was too large for my fingers.

                              @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.

                                    one of these popped up for $25 and I've been wanting one for years so I had to do it

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