    Exclamation iButton - Very cool product

    Hey all!

    In a recent thread about biometrics and secure access, an interesting URL was posted ( http://www.ibutton.com ) I looked through the site and was immediately intrigued.

    Five minutes after visiting the site, I purchased a developer's kit. The kit should be in my possession within a few days.

    The point of all this: the possibilities are endless with this type of device. From starter/ignition/fuel pump kills to PKI.

    As I work with the hardware, I will be sure to keep everybody updated.

    Cheers!

    WoW! I'm definately investing in a developer's kit. My thoughts are to buy a tiny board and having that run of the battery constantly. Once you get into your car you flash your IButton onto the receptor which then will sync with tiny board. After this (tiny board)it will send a signal through a hacked serial cable to start computer. Another thought is to have the tiny board trigger the ignition of your car, but this seems like a hard task. Does anyone have thoughts on this?

    How is this different than a 'secure' key?
    The i-button has been out for a long time. You still have to make electrical contact to it. You still have to take it along with you.

    BMWs and Mercedes already use RF transponders that also log service information. No contact to get flakey and wear out.

    It is similar to the Mobil Speedpass in some areas - though very different in approach.

    The speed pass is a passive transponder (if I'm not mistaken) and is only "activated" when placed near a "stimulus field" [data collector/power unit]. The iButton however requires mechanical/electrical contact to function - not nearly as conveniant, though not such a downfall either.

    time to bring this thread back from the dead...

    i have been looking into the ibutton for many uses as well, i would like to mod a computer so that only specific ibuttons could turn it on. IE replace the power button so they only way to boot the computer at all is by using the ibutton.

    i am also looking at it for the ignition and locks to my car. if anyone has done any of these things or has any ideas i would love some feedback

    does anyone know if/how this or this can be wired up to boot your computer when the correct ibutton is detected? i believe it only outputs power when the right one is detected.


    i am also thinking about using something like this to control access to my case in the car to prevent access to the actual computer by any would be theives (build it in a tucked away steel case and install an electronic lock opened by an ibutton. when my friend heard about that he asked me to find out if there was a way to use this to secure his desktop case (basicly a way to use small electric locks that will be opened by the door thing i posted above so if anyone has a clue please let me know and if not i will tell my friend to it

    The only problem with the ignition part is ... you could start the car but you would stilll need your key to unlock the steering column.

    i was thinking about putting remote start in my car, would it be possible to use this that to bypass the need for a key to unlock the steering column or does that have the same problem. and does anyone else know how i could make that work? i have read about rent car companies that have done this with ibutton and what not, but not having much luck with on how to, i hope google is not turning on me, we used to be such good friends
