Integrating the EHIC Scanner UI

The EHIC Scanner is based on the OCR feature and thus requires the proper installation of the OCR language files deu.traineddata and eng.traineddata (aka. blob files). For more details on how to set up OCR language files please refer to the OCR section.

Use the plugin API method ScanbotSdk.UI.startEHICScanner() to start the EHIC Scanner UI.

import { ScanbotSDK, HealthInsuranceCardScannerConfiguration } from 'capacitor-plugin-scanbot-sdk';
// Always make sure you have a valid license on runtime via ScanbotSDK.getLicenseInfo()
if (!licenseCheckMethod()) { return; }

const configuration: HealthInsuranceCardScannerConfiguration = {
// Customize colors, text resources, behavior, etc..
finderTextHint: 'Please hold your phone over the back of your Health Insurance Card.',
orientationLockMode: 'PORTRAIT',
// see further configs ...
};

const result = await ScanbotSDK.startEHICScanner(configuration);

if (result.status === 'CANCELED') {
// user has canceled the scanning operation
return;
}

// handle the extracted data fields
// result.ehicResult.fields[n]...
///...

Handling the Result

The result object contains the following fields:

  • status: 'OK' if EHIC data was extracted, 'CANCELED' if the user canceled the operation (tapped on the "cancel" button).
  • ehicResult.fields[]: An array of EHIC fields. Each field is an object with the following properties:
    • field.type - the field type
    • field.value - the value of the field
    • field.confidence - confidence in the accuracy of value
