## Overview
-NFC service uses the respective libnfc package to detect the presence of NFC tags and singal via an event
+NFC service uses neard package to detect the presence of NFC tags and signal clients via an event.
+The NDEF data shall include a text record ('uid') to keep compatibility with the existing agl-service-identity-agent.
