+
+#### Overview
+
+This project is a sample app showing how to use CoreNFC with NDEF tags or hardware. It was tested with a limited number of NDEF tags. 
+
+From the main screen, tapping scan will show the system UI for NFC scanning. Hold the tag or device near the top of the phone. A scan result will appear. You can drill down into the message and see individual message records.
