ParticipantHello 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.

ParticipantThanks 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
