# How to Set Up the Sunmi Barcode Scanner With Munchi POS

> Learn how to assign SKU codes and configure the Sunmi barcode scanner hardware so you can ring up products by scanning them at the POS.

The Sunmi barcode scanner lets you ring up products instantly by scanning their barcodes at the POS. To get everything working, you first need to assign SKU codes to your products in the Munchi dashboard, then configure the scanner hardware, and finally enable barcode scanning in your POS settings.

<Note>
  SKU codes must be assigned to products in the Munchi dashboard **before** scanning will work. The scanner looks up items by their SKU, so any product without one will not be recognised at the POS.
</Note>

## Step 1: Assign SKU Codes to Your Products

<Steps>
  <Step title="Open the Munchi dashboard">
    Go to [https://dashboard.gomunchi.com/](https://dashboard.gomunchi.com/) and click on **Products**.
  </Step>

  <Step title="Select a product">
    Click the product you want to make scannable.
  </Step>

  <Step title="Enter the SKU">
    In the product details, enter the product's **Stock Keeping Unit (SKU)** code in the designated field.
  </Step>

  <Step title="Save the product">
    Click **Save** to apply the SKU. Repeat this process for every product you want to scan at the POS.
  </Step>
</Steps>

## Step 2: Connect the Scanner Hardware

<Steps>
  <Step title="Plug in the scanner">
    Connect the scanner cable to the adapter, then plug the other end into the POS tablet's port.
  </Step>

  <Step title="Run the scanner setup sequence">
    Using the scanner, scan the following barcodes in order:

    1. **Enter setup** barcode
    2. **Restore all factory defaults** barcode
    3. **Exit setup** barcode

    This resets the scanner to the correct configuration for use with Munchi POS.
  </Step>
</Steps>

## Step 3: Enable Barcode Scanning in POS Settings

<Steps>
  <Step title="Open POS Settings">
    Navigate to **Settings** in your POS app.
  </Step>

  <Step title="Go to System">
    Tap **System** from the settings menu.
  </Step>

  <Step title="Turn on Barcode Scanning">
    Toggle **Barcode scanning** to the on position. Your POS is now ready to accept scanned products.
