Hi Mike,

The unique method to know if one card is COMP128 v1 or V2 is search the ki by collissions (The normal method).

By Color, Size, weight or "taste" you can´t know what algorimth have you card.

If you card have a limit or counter in the authenticate instruccion, you can broken this with a search, but I am sure that your distribuitor will change this SIM (because then can´t know that this card are broken for this)....
