+
+.. |EPC| replace:: :abbr:`EPC (electronic product code)`
+
+RFID stands for Radio Frequency Identification. RFID enables the tracking of items using radio
+waves: RFID tags are attached to products in inventory, and RFID readers can read those tags to
+transmit information to a computer. RFID helps automate processes by keeping inventory accurate and
+tracking internal and external moves.
+
+RFID tags transmit electronic product codes (|EPC|), which are unique identifiers to distinguish
+individual items. The |EPC| in Odoo is based on GS1 standards to consistently identify products
+worldwide. GS1 nomenclature establishes common rules for encoding information within a barcode to
+facilitate the global exchange of goods.
+
+.. seealso::
+   :doc:`../operations/gs1_nomenclature`
+
+Hardware
+========
+
+The following are required to begin working with RFID in Odoo:
+
+- Zebra TCX Series mobile computer, or
+- Android Smartphone
+
+Paired with:
+
+- Zebra RFD40 (can read and write RFID tags)
+
+Configuration
+=============
+
+Before using RFID tags to manage inventory, the Android Package Kit (APK) with RFID support must be
+installed on the mobile computer or smartphone.
+
+.. important::
+   Before installing the APK on an individual device, first enable the ability to install unknown
+   apps in the device settings. Find this setting in the device's :guilabel:`App` or :guilabel:`App
+   & Notification` settings, under the :guilabel:`Special access` or :guilabel:`Special app access`
+   section.
+
+Then, download the APK. On the :guilabel:`Downloads` page, under the :guilabel:`Mobile Application`
+section, click :guilabel:`Download` next to the :guilabel:`Android` option, then select
+:guilabel:`Download APK (with Zebra RFID support)` from the drop-down menu. Download this file via a
+computer and transfer the APK via USB or Bluetooth, or use the device's web browser to download the
+APK.
+
+.. image:: rfid/download-apk.png
+   :alt: Download the APK from the Download page.
+
+Install the APK. If :guilabel:`Install unknown apps` is enabled for the device's web browser,
+install the APK directly from the browser download notification. If :guilabel:`Install unknown apps`
+is enabled for the device's file manager, open it and navigate to the location where the file is
+stored, then tap it to install the APK.
+
+Then, when reading or writing RFID tags, ensure that the Zebra device and the smart device are
+paired and connected.
+
+Set a compatible barcode
+========================
+
+Before you can manage inventory using RFID tags, a compatible barcode must be assigned to the
+products. Set the product barcode in the product form.
+
+.. seealso::
+   :ref:`Set product barcodes <inventory/barcode/set-barcodes>`
+
+To work with RFID, the product barcode must be GTIN-14-compatible, and inventory tracking must be
+enabled for the product. Product barcodes that are not GTIN-14-compatible must be upgraded to work
+with RFID.
+
+.. note::
+    Tracking by serial number or lots does not need to be enabled for this feature to work properly.
+
+Limitations
+===========
+
+- The serial number that is part of the |EPC| must only be numeric, as SGTIN-96 is the only
+  supported encoding scheme for RFID tags in Odoo. Alphanumeric serial numbers are **not**
+  supported.
+- For products tracked by lot, the lot can be scanned in, but it will be considered as one lot with
+  a quantity of `1`. It does not count individual products in a receipt.
+- Only ultra-high frequency (UHF) RFID tags are supported.
+- Products need to be GS1-registered because barcodes must be unique.
