EHIC Scanner | Flutter Document Scanner

Introduction​

The Scanbot SDK comes with an essential camera view, additional views for extending the camera functionality and a detector classes that handle all the camera and detection implementation details for you.

The Scanbot SDK provides the ability to scan and extract content from European Health Insurance Cards (EHIC), a.k.a. elektronische Gesundheitskarten (eGK).

The following fields are supported:

  • SURNAME
  • GIVEN_NAME
  • DATE_OF_BIRTH
  • PERSONAL_IDENTIFICATION_NUMBER
  • INSTITUTION_NUMBER
  • INSTITUTION_NAME
  • CARD_NUMBER
  • CARD_EXPIRATION_DATE
  • COUNTRY

The EHIC scanner is available both as an RTU-UI Component (types of components are explained here).

Take a look at our Example Apps to see how to integrate the European Health Insurance Card Scanner.

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 ScanbotSdkUi.startEhicScanner(config) to start the EHIC Scanner UI.

var config = HealthInsuranceScannerConfiguration(
  topBarBackgroundColor: Colors.pink,
  cameraOverlayColor: Colors.black.withAlpha(150),
  topBarButtonsColor: Colors.white70,
  ...
);
var result = await ScanbotSdkUi.startEhicScanner(config);
// result.fields ...

  • result.operationResult -

    • SUCCESS if EHIC data was detected
    • ERROR if an error occurred
    • CANCELED if the user canceled the operation (tapped on the "cancel" button)

  • result.fields - an array of recognized EHIC fields. Each field is an object with the following properties:

  • status - one of folowing values SUCCESS,FAILED_DETECTION,FAILED_VALIDATION.
