Hi Support,
The main reason I'm trying to do this is to have 4000 cards back in default factory state that have been personalized mistakenly with the wrong app and keys.
They were meant to be used on an older system that is different to what we have now as I don't have the capacity to develop a legacy app that would be compatible with the other system. The older system also doesn't have all the required source available so I don't even know where to start.
But having the cards back in factory default would solve the immediate issue for me.
Thanks for all your time and help so far.
Regards,
Sheldon
