Hi SRJCracker,
I assume you mean Mifare DESFire EV1 "card emulation" capabilities (because nRF52 cannot handle NFC reader mode), then answer is: yes, in theory you could implement ISO7816-4 APDU protocol according to DESFire specificaiton on top of ISO14443-1/2/3/4 stack provided by nRF52 HW. However it won't support DESFire native protocols (see details e.g. here) and you would also face licensing issues I believe (as far as I know you cannot freely implement and use DESFire brand, it's subject of license agreement with NXP).
However Nordic's SDK supports NFC Forum (NDEF) Type 4 tag which effectively implements subset of DESFire commands and functionality. So if you are fine with select app/file, read and write capabilities then you can use it straight away.
Cheers Jan
thank you so much Jan!! Can you give some more brief on how payment card emulation is carried out on nrf52840 board ?
