Hi @jr_hernandez
we don't have a porting guider for ESP32. But the NXP Reader library is encapsulated into layers and components written in ANSI C. The library structure provides a modular way of programming and setting up to the reader interface.
It is easy to porting to other MCUs.
pleaser refer to docs\NxpNfcRdLib\NXP-NFCReaderLibrary-apiguide
for more details
Regards
Daniel
