# 条形码 / QR 码提取

## **概述**

此功能可自动提取文档中嵌入的**条形码和 QR 码**信息。这是一项全开或全关的设置——启用后会同时提取这两种代码。

{% hint style="info" %}
\*\*相关内容：\*\*如需在验证文档时手动读取条形码 / QR 码的值并将其分配给某个字段，请参阅 [条形码分配](/chinese/guan-li-yu-she-zhi/settings/document-processing/module/barcode-assignment.md)。
{% endhint %}

## 如何启用条形码 / QR 码提取

请按以下步骤启用条形码 / QR 码提取功能：

1. **前往设置**：
   * 在仪表板中，前往**设置**。
   * 选择**文档处理**，然后选择**模块**。
2. **启用此功能**：
   * 向下滚动，找到**条形码 / QR 码提取**选项。
   * 切换滑块以启用条形码 / QR 码提取。

## **支持的代码类型**

DocBits 支持提取以下代码类型：

* **QR-CODE**
* **EAN-2**、**EAN-5**、**EAN-8**、**EAN-13**
* **UPC-A**、**UPC-E**
* **ISBN-10**、**ISBN-13**
* **COMPOSITE**
* **I25**
* **DATABAR**、**DATABAR-EXP**
* **CODABAR**
* **CODE-39**、**CODE-93**、**CODE-128**
* **PDF-417**
* **SQ-CODE**

## 付款 QR 码标准

除了通用 QR 码解码之外，DocBits 还能识别 **七种不同的付款 QR 码标准**，并将其中的付款字段自动提取到文档 API 响应中。客户无需再手动解码这些 QR 字符串——每种标准都有自己的字段前缀（例如 `swissqr_*`、`girocode_*`），因此这些值可以直接用于匹配、验证和导出。

\*\*检测会自动进行。\*\*系统会检查每个解码后的 QR 字符串是否包含其特有前缀（例如，Swiss QR Bill v2.0 的 `SPC\n0200`，PagoPA 的 `PAGOPA|002|`），并且只会将识别出的标准解析为结构化字段。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.docbits.com/chinese/guan-li-yu-she-zhi/settings/document-processing/module/bar-code-qr-code-extraction.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
