# Bar Code Extractions

## Overview

This feature enables automatic detection of barcodes on documents. When activated, all supported barcode types are scanned and extracted during processing.

## How to Enable Bar-Code Extraction

To enable the Bar-Code Extraction feature, follow these steps:

1. **Navigate to Settings**:
   * From the Dashboard, go to **Settings**.
   * Select **Document Processing** and then choose **Module**.
2. **Enable the Feature**:
   * Scroll down to locate the **Bar-Code Extraction** option.
   * Toggle the slider to enable Bar-Code Extraction.\\

## **Additional Settings**

### **Barcode Assignment**

#### **Purpose:** Allows validators to manually assign an extracted barcode value to a specific document field during field validation.

#### How to Enable **Barcode Assignment**

To enable the **Barcode Assignment** feature, follow these steps:

1. **Navigate to Settings**:
   * From the Dashboard, go to **Settings**.
   * Select **Document Processing** and then choose **Module**.
2. **Enable the Feature**:
   * Scroll down to locate the **Barcode Assignment** option.
   * Toggle the slider to enable **Barcode Assignment**.\\

#### **How it works:**

* Enables an “Assign Barcode” option in the field validation screen.\\
* Users can select a detected barcode value and map it to a document field like PO Number or Invoice Number.\\

### Split of Document by Barcode / QR Code

**Purpose:** Automatically splits multi-page documents into separate documents based on the presence of specific barcodes or QR codes.

#### How to Enable Split of Document by Barcode / QR Code

To enable the **Split of Document by Barcode / QR Code feature**, follow these steps:

1. **Navigate to Settings**:
   * From the Dashboard, go to **Settings**.
   * Select **Document Processing** and then choose **Classification and Extraction**.
2. **Enable the Feature**:
   * Locate the **Document Splitting** option.
   * For **Split**, select **Split by Barcode / QR Code**.
   * For **Barcode Type**, choose one or more supported barcode types from the list.
   * For **Barcode Pattern**, define the pattern that should trigger a split. You can use a **regular expression** (regex) to match dynamic barcode values.

**How it works:**

* You select the barcode types that should trigger a split.
* You define a pattern the barcode must match — this can be a fixed string or a regex (e.g., `^INV\d{6}$` to match barcodes like `INV123456`).
* During document processing, each time a page contains a matching barcode, a **new document is created** starting from that page.

### Supported Code Types

See the [Overview Page](/administration-and-setup/settings/document-processing/module/bar-code-qr-code-extraction.md) for the full list of supported barcode and QR code formats.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.docbits.com/administration-and-setup/settings/document-processing/module/bar-code-qr-code-extraction/bar-code-extractions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
