I was wondering how the number on the back of a HID IoProx tag is generated. Is it possible to generate those numbers if i already know the FC and bit length and write my own card number?

The last series of the two (the long set) has to do with the internal manufacturing of the card, and is not part of the "permission coding" - only the concatenated FC and first series of numbers FC are relevant is my understanding. You end up with a ten character HEX value.
