+.. note::
+    There is currently no official commercial NFC commissioner smartphone application available.
+    To test NFC-based commissioning, you need an NFC commissioner that implements the Matter NFC Transport Layer (NTL).
+    You can develop your own commissioner application based on the Matter 1.6 specification (`Matter Core Specification`_).
+
+To commission the |matter_type| over NFC using a Nordic Semiconductor DK, complete the following steps:
+
+.. rst-class:: numbered-step
+
+Build the |matter_type| with the NFC commissioning support
+----------------------------------------------------------
+
+Ensure that the |matter_type| is built with NFC-based commissioning enabled.
+See :ref:`matter_configuring_nfc_commissioning` for the required Kconfig options and supported DK targets.
+
+.. rst-class:: numbered-step
+
+Prepare the Matter network
+--------------------------
+
+Check whether Thread dataset or Wi-Fi credentials are configured.
+
+.. rst-class:: numbered-step
+
+Flash the DK
+------------
+
+Flash the DK with the proper firmware and connect a terminal emulator to monitor the UART log.
+When the Matter server finishes initializing, the device automatically starts NFC tag emulation and serves an NDEF onboarding payload with the NFC rendezvous flag.
+No button press is required to start NFC commissioning.
+
+.. rst-class:: numbered-step
+
+Start the commissioning process
+-------------------------------
+
+On a smartphone with an NFC commissioner application that supports Matter NTL, tap the NFC antenna area on the DK to start the commissioning session.
+
+Keep the smartphone within NFC range for the duration of the commissioning exchange.
+The required hold time depends on the network variant:
+
+.. tabs::
+
+   .. group-tab:: Matter over Thread
+
+      Hold the tap for at least **9 seconds**.
+
+   .. group-tab:: Matter over Wi-Fi
+
+      Hold the tap for at least **20 seconds**.
+
+Keep the smartphone in the NFC field until the commissioner application indicates that commissioning has completed successfully.
+After commissioning is finished, NFC tag emulation on the DK will automatically stop.
+
+If the commissioner loses connection with the device during the process, wait until the failsafe mechanism is triggered before attempting commissioning again.
+You will see the following UART log messages:
+
+.. code-block:: console
+
+   I: 5419 [DL]NFC field lost: the NFC Reader/Writer moved away
+   I: 5424 [DL]NFC tag emulation paused until fail-safe completes
+
+The failsafe timeout depends on the commissioner configuration.
+
+.. rst-class:: numbered-step
+
+Control the device
+------------------
+
+Use the commissioner application to control the device and verify that the expected clusters and attributes are accessible.
