Fair enough. I also am now in the spirit of thinking that I should just do what makes me enjoy my switch the most now and for the nearest future
Also, having already updated it once, it might already be past the point where it is no more exploitable (if ever it will be), so there even might be no reason to overthink all the thing.
Just for the sake of having more knowledge of what I am doing, do you know if the update is applied at time of firmware upgrade or if it is done when the reader is actually being used?
And thank you again for helping me understand (almost) everything I am doing. So I will not need to come back to this thread in future for upgrades and whatever. Or maybe I will be able to be one giving some answers instead of just making questions
