The NFC Forum has added the final major component to its device certification with the addition of analog testing, but the impact of the development on handset makers’ willingness to submit their devices for certification remains to be seen.

Sources have said that smartphone manufacturers were waiting for the analog piece before submitting their devices for NFC Forum-approved testing and certification.
