This document discusses NFC concepts, Windows 8/Phone 8 NFC applications, NDEF format, NDEF records, NFC tags, and the Windows.Networking.Proximity namespace for NFC on Windows platforms. It describes NFC communication modes and operating modes, how NFC can enable device pairing and data transfer in Windows 8 and Phone 8. It also covers different NFC tag types and forums, and common NFC chip compatibility issues.
