Hello, This is NXP's Technical Support.
Thank you very much for writing.
EMVCo typically requires that the whole solution meets the standards. Theese refers to the NFC reader IC, MCU host, and the SW stack. But, it is the whole solution the one that has to pass the tests conducted by EMVCo. This is for the sake of ensuring that all the elements of the solution are secure and meet the standards.
Some of our ICs are precertified because the NFC front end can meet EMVCo's tests but, this doesn't mean that once you developed your solution, you don't have to perform these tests.
Best Regards,
Fabian
