(Fell asleep after reading this, guess I need more)
Yeah I registered one of the included fob/cards, confirmed it worked a few times, copied it to my implant, confirmed that with TagInfo, and couldn’t get it even with the help of an xFD, your field detector, and one of your stickers (paired with scotch tape to avoid wasting one).
It also throws a red light and a different beep if an unregistered mifare 1k gets put up to it, and it didn’t do that either.
