About the Scanbot Barcode Scanner SDK

The Scanbot Barcode Scanner SDK provides intuitive APIs to integrate fast, reliable barcode scanning into your React Native app.

It works entirely offline and scans barcodes in 0.04 seconds, even in challenging conditions like poor lighting or with damaged codes.

💡 For more details, check out our documentation or see our example app.

Supported barcode types

Our library supports all common 1D and 2D barcodes and multiple postal symbologies, including:

Barcode type	Symbologies
1D Barcodes	EAN, UPC, Code 128, GS1-128, Code 39, Codabar, ITF, Code 25, Code 32, Code 93, Code 11, MSI Plessey, Standard 2 of 5, IATA 2 of 5, Databar (RSS), GS1 Composite
2D Barcodes	QR Code, Micro QR Code, Aztec Code, PDF417 Code, Data Matrix Code, GiroCode, PPN, UDI, Royal Mail Mailmark, MaxiCode

How to use the SDK

Installation

Requirements

Check out our documentation for a full overview of our SDK's requirements.

Install steps

Install the Scanbot Barcode Scanner SDK module by running:

1# Using Yarn
2yarn add react-native-scanbot-barcode-scanner-sdk
3
4# Using npm
5npm install react-native-scanbot-barcode-scanner-sdk
6
7# Using Expo
8npx expo install react-native-scanbot-barcode-scanner-sdk

Expo integration

Expo projects require a development build. Configure the project using our config plugin by adding this to your app config file:

"plugins": [
  [
    "react-native-scanbot-barcode-scanner-sdk",
    {
      "iOSCameraUsageDescription": "Barcode Camera permissions",
      "androidCameraPermission": true,
      "androidCameraFeature": true,
      "mavenURLs": true
    }
  ]
],

💡 See our full installation guide for complete details.

Camera permissions

Our SDK needs camera access to scan from a live camera stream.

Note: If you use Expo, the permissions can be configured using our config plugin, and this step can be skipped.

Android

Add these camera permissions to your android/app/src/main/AndroidManifest.xml:

1<uses-permission android:name="android.permission.CAMERA" />
2<uses-feature android:name="android.hardware.camera" />

We added the uses-feature tag for better recognition in the Google Play Store (learn more). Our Ready-to-Use UI Components handle runtime permissions automatically.

iOS

Add this camera permission description to ios/{projectName}/Info.plist inside the element:

1<key>NSCameraUsageDescription</key>
2<string>Camera permission is needed to scan barcodes</string>

SDK initialization

Initialize the SDK before using any features, ideally when your app launches.

Add this import to the top of your file:

1import ScanbotBarcodeSDK from 'react-native-scanbot-barcode-scanner-sdk';

Initialize the SDK with:

1ScanbotBarcodeSDK
2.initializeSdk({ licenseKey: "" })
3.then(result => console.log(result))
4.catch(err => console.log(err));

💡 You can test the SDK without a license key for 60 seconds per app session. Need longer testing? Get your free trial license key.

Barcode scanner setup

Scanning modes

In our ready-to-use UI, the Scanbot Barcode Scanner SDK offers the following scan modes right-out-of-the-box.

Single Scanning

This is the default scanning mode. It is optimized for detecting a single barcode at a time.

1/**
2 * Instantiate a configuration object of BarcodeScannerScreenConfiguration and
3 * start the barcode scanner with the configuration
4 */
5const config = new BarcodeScannerScreenConfiguration();
6const result = await ScanbotBarcodeSDK.startBarcodeScanner(config);

Multi Scanning

The barcode scanner can also be configured to scan multiple barcodes in one go without closing the scanning screen. It can also count the scanned items.

1/**
2 * Instantiate a configuration object of BarcodeScannerScreenConfiguration and
3 * start the barcode scanner with the configuration
4 */
5const config = new BarcodeScannerScreenConfiguration();
6config.useCase = new MultipleScanningMode();
7const result = await ScanbotBarcodeSDK.startBarcodeScanner(config);

Find & Pick

Given one or more barcodes, the SDK visually highlights and scans the correct items for your users. It automatically selects the barcode with the right barcode value from your camera feed.

1/**
2 * Instantiate a configuration object of BarcodeScannerScreenConfiguration and
3 * start the barcode scanner with the configuration
4 */
5const config = new BarcodeScannerScreenConfiguration();
6config.useCase = new FindAndPickScanningMode();
7config.useCase.expectedBarcodes = [
8  new ExpectedBarcode({
9    barcodeValue: '123456',
10    title: 'numeric barcode',
11    count: 4,
12    image: 'https://avatars.githubusercontent.com/u/1454920',
13  }),
14  new ExpectedBarcode({
15    barcodeValue: 'SCANBOT',
16    title: 'value barcode',
17    count: 3,
18    image: 'https://avatars.githubusercontent.com/u/1454920',
19  }),
20];
21const result = await ScanbotBarcodeSDK.startBarcodeScanner(config);

Configuration options

The Scanbot React Native Barcode Scanner SDK offers numerous configuration options:

• Barcode filters: Apply filters by barcode type or content, with regex pattern support to capture only relevant barcodes.

• AR overlay: Optional feature providing real-time barcode highlighting, preview, and tap-to-select functionality. Recognized barcodes are highlighted with customizable frames and text.

• Barcode parsers: Extract structured information from 2D barcodes like QR and Data Matrix codes. These include parsers for documents such as driving licenses (AAMVA), boarding passes, medical certificates, SEPA forms, Swiss QR codes, and vCard business cards.

• Scanning barcodes from an image: Detect barcodes from still images in JPG or other formats, with support for single and multi-image detection.

UI customization

Customize the UI to match your app's look and feel. Please refer to our documentation for a full overview of the visual configuration options.

• Configuring UI Elements: Tailor interface elements with custom guidance text, enable or disable the Top Bar, or configure the Action Bar with features like Flashlight and Zoom buttons.

• Palette: Configure your UI's color palette to match your brand design for a cohesive user experience.

• Localization: Easily localize strings displayed on buttons, labels, and text fields.

10config.localization.userGuidance = 'Please hold your camera over the barcode';

12// Adjusting the text on the 'Cancel' Button
13config.localization.topBarCancelButton = 'Dismiss';

15// Changing the color palette
16config.palette.sbColorPrimary = '#000000';
17config.palette.sbColorNegative = '#ff3737';
