Answers
Common questions
How do the KF01, KF02 and KF03 differ?
Same fob shell, different chip. The grey KF01 has a Fudan chip that is MIFARE Classic compatible; the orange KF02 has a genuine NXP MIFARE Classic S50 chip; the blue KF03 has an NXP MIFARE DESFire EV3 chip with AES encryption, 8 KB memory and EAL5+ certification, the hardest of the three to copy.
Is this one fob or a pack?

Is it the same chip as the Akuvox S50 card?
