Arduino compatible I2C chip that reads ISO15693 - convert external C library?

Does anyone have experience with a library that supports a tag reader reading ISO15693 cards? For example, the CLRC663, or TRF7970A?

The CLR663 for example comes with a comprehensive library, detailed here: http://www.nxp.com/documents/user_manual/UM10663.pdf http://www.nxp.com/documents/user_manual/UM10721.pdf And the library itself is here: http://www.nxp.com/documents/software/200310.zip Would this work in Arduino IDE directly?

The PN532, there's a lot of amazing code out there, but that IC unfortunately does not read 15693 cards!

I saw a couple posts about this but they seem inconclusive.

When you find a module with a suitable (SPI, I2C…) interface, consult its data sheet for the command and data formats. Then write your own library for that module, implementing the commands you need.

I wrote this library https://github.com/ohait/jmy6xx for this module http://www.jinmuyu.com/hf-rfid-modules/jmy622.html

It is still under development, but I'm actively working on it now
