The NFC functions as a tag and is not considered an "intentional radiator". As such, RF certification is not required. Rigado modules carry the necessary RF transmitter certifications for various world regions.
As with any electronic device, the end-device will require standard electromagnetic compatibility tests (EMC) for unintentional radiator emissions, and susceptibility.
It is always recommended to consult with an accredited RF test facility to ensure compliance with the latest regulations for the intended world regions.
