Hi,
it's necessary to certify the NFC of the nrf52? And how we do it?
Thank you!
I don't think it's necessary. Unless your country has legal requirements that state you have to or if you're selling it in a product.
Edit: I did mean to post this as a comment as this isn't a full answer to your questions.
