    Hello Everyone.

    so I’ve located a smart card and it’s on its way.

    I will attempt to extract the data and post my results here…

    Regards

    Rik

    must be some way of doing a memory dump off the card if you can decipher it

    …most likely the Hotpoint service tool/interface deletes it, simply so the Engineers can’t run a snide side business and deprive Hotpoint of revenue.

    I’m not aware of self destructing Smart Cards.

    Thanks for your reply Dave!

    Perhaps I could extract it but would need to find one first, can’t seem to locate one.
    From what I’ve learned, these Smart Cards are a ‘one shot’ access so no room for errors during extraction.

    The EEPROM is very easy to read from a donor, such a shame we have to go to such efforts to retrieve what we already own.

    SkyProg has done a great job of building a repository of EEPROMS, but unfortunately with so many models and it does take a little know how in order to read the EEPROM.

    Hopefully someone here can help with a donor or affordable spare.

    Have a great day…

    kind regards

    Rik
