I'm trying to emulate a MIFARE DESfire card on my Android phone but I simply can't pick up any commands from the reader. I have a PN532 NFC board available and different phones with NFC.
As described here it is only possible to emulate ISO/IEC 7816-4 if the readers architecture works in a specific way.
So how can I pick up these commands from the reader?
I decided to buy a pn532 board to run this program https://github.com/nfc-tools/libnfc/blob/master/utils/nfc-emulate-forum-tag4.c
In this way i could detect the readers' select package.
