> The paper seems to found a hardcoded A/B key A396EFA4E24F for a particular brand of RFID cards (I just skimped the paper and its been years since I worked on RFID. I might be wrong on the detail).
Actually, if I understood the paper well, the same key worked also on older, non-Chinese cards like those produced by NXP. Why, that's a big question.
