Scandit QR / Barcode

The Scandit QR Code and Barcode Scanner plugin enables barcode scanning directly within your application using the device camera. This plugin extends the functionality of our basic version of Barcode Scanner with additional capabilities provided by the Scandit iOS and Android SDKs.

In order to use this plugin an active Scandit license is required.

Implementation Guide

Plugin Configuration

Before implementing this feature, ensure that the premium module is integrated into your application. Additionally, you will need to add your license key to the plugin configuration as it is required to use the native iOS and Android SDKs of Scandit.

You can find you license key in Scandit under Projects & license keys > Project > License keys as shown in the picture below.

Insert the license key into the plugin configuration using Advanced Mode:

JavaScript Bridge Methods

Define a Scan Callback

To initiate a barcode scan, define a JavaScript function to handle the scanned data. For example:

function scandit_result(data) { 
    console.log('Scanned barcode ' + data.code + ' of type ' + data.type); 
}

Start a Scan

Use the following command to start a barcode scan via the Median JavaScript Bridge:

↔️Median JavaScript Bridge

To initiate a scan, open the URL:

JavaScript

// returns promise
median.scanditBarcode.scan({'callback': scandit_result});

Tip: Some JavaScript Bridge commands return promises. These are indicated in comments for easy identification. Learn More.

Supported Barcode Symbologies

By default, the scanner supports the following barcode symbologies:

• ean13
• upc12
• ean8
• upce
• code39
• code128
• itf
• qr
• datamatrix
• pdf417

Restricting to Specific Symbologies

To restrict the scanner to specific barcode types, provide a comma-separated list of desired symbologies in the symbologies parameter.

For example, to scan only QR codes and PDF417 barcodes:

↔️Median JavaScript Bridge

JavaScript

// returns promise
median.scanditBarcode.scan({'callback': scandit_result, 'symbologies': 'qr, pdf417'});

Using a Parser for Specialized Data

Certain symbologies, such as Code 128, require a parser to correctly interpret the scanned data. Add the parser parameter when calling median.scanditBarcode.scan.

For example, to scan QR codes and Code 128 barcodes with the dlid parser:

↔️Median JavaScript Bridge

JavaScript

// returns promise
median.scanditBarcode.scan({'callback': scandit_result, 'symbologies': 'qr, code128', 'parser': 'dlid'});
