1. Download and install the Maotai safety traceability application, which is officially launched by Maotai and can be searched and downloaded by all major application stores.

2. Turn on the NFC function of the mobile phone. Some modern smartphones are equipped with NFC function, but they need to be turned on manually in the device settings.

3. Align the NFC sensing area on the back of the mobile phone with the RFID tag on the bottle cap of Moutai. When the phone approaches, the application will automatically pop up relevant information.

4. Check and verify the information displayed in the application. If the information is consistent with the label information on the bottle, then this bottle of Maotai is real.
