How to create an NFC tag using Arduino Nano?

Question

Arduino

Good afternoon, gentlemen.
There is the following task: it is necessary to create an NFC tag for reading / writing data using Arduino Nano v.3.0 ATmega328P. A solution was found on the Internet , however, if everything is clear in terms of the implementation of the scheme, then nothing is clear to me with the code , since I encountered such a task for the first time.
Therefore, the question is:
- is there any ready-made solution for Arduino for processing a signal transmitted via NFC?
- if there is no solution, what can help in writing the code?
- What materials can generally help in solving the problem?
PS: I heard about NFC Shield and Adafruit, while this is a fallback.
Thank you!

Listen, do you really need it in this form? In no way do I want to offend you, but creating your own nfc tag at a low level is not an easy task, and I honestly am not sure that you will solve it.
Make it much easier - take a ready solution from ST: www.st.com/web/en/catalog/mmc/FM76/CL1766/SC1412/SS851 they are even called " dynamic RFID tags". The bottom line is simple, this chip is a regular EEPROM with an I2C interface, only it also has an antenna output. It turns out that you can communicate with this micro-memory both via I2C and RFID. All that remains to be done is to write the necessary data via I2C into it with an arduino, and they will become available via RFID (and vice versa too).
