HI, I am gettign an ATR : A card is present. ATR: 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 *FF 40* 00 00 00 00 D4 .
I dont htink it emulated the card.Does it.For 1k/4k Mifare Classic Card it has to be 00 01(Mifare 1k) or 00 02(Mifare 1k) instead of *FF 40* .PLz correct my understanding.I have used the patches to enable to the phone in Card emulation mode.
