+# NFC Technical Information #
+*Placeholder*
+
+The Android Open-Source Project also includes an NFC implementation. Unlike
+the Android Bluetooth stack, much of the Android NFC stack is new code
+originally contributed to the Android Open-Source Project. This code links the
+Android NFC API to a device's NFC hardware. This section also includes
+information on related Android technologies, such as the simple NDEF Push
+Protocol.
