Smartphone as an NFC reader to connect to a PC?

Question

NFC

Hello! Interested in the answer to the question: are there ways to convert a smartphone with an NFC module into an NFC reader for communicating with a PC? It is necessary to calculate keys A and B for a card with a Mifare Classic chip (not for illegal purposes, moralizing is still not necessary). Well, or are there ways to pick up crypto keys in a different way that does not take several years? Thank you!

exists,
software on the phone + software on the computer
or just break the reader and solder it to the USB for example
