Version 7 plugin usage

The performScan method

The performScan method launches the BlinkID scanning process with the default UX properties.
It takes the following parameters:

1. BlinkID SDK settings
2. BlinkID session settings
3. The optional ClassFilter object for filtering documents.

BlinkID SDK Settings - BlinkIdSdkSettings: the class that contains all of the available SDK settings. It contains settings for the license key, and how the models, that the SDK needs for the scanning process, should be obtained.

BlinkID Session Settings - BlinkIdSessionSettings: the class that contains various settings for the scanning session. It contains the settings for the ScanningMode and BlinkIdScanningSettings, which define various parameters that control the scanning process.

The optional ClassFilter class - ClassFilter: the class which controls which documents will be accepted or reject for information extraction during the scanning session.

• The implementation of the performScan method can be viewed here in the blinkid_flutter_method_channel.dart file.

The performDirectApiScanning method

The performDirectApiScan method launches the BlinkID scanning process inteded for information extraction from static images.
It takes the following parameters:

1. BlinkID SDK settings
2. BlinkID session settings
3. First image string in the Base64 format
4. The optional second image string in the Base64 format

BlinkID SDK Settings - BlinkIdSdkSettings: the class that contains all of the available SDK settings. It contains settings for the license key, and how the models, that the SDK needs for the scanning process, should be obtained.

BlinkID Session Settings - BlinkIdSessionSettings: the class that contains various settings for the scanning session. It contains the settings for the [ScanningMode] and [BlinkIdScanningSettings], which define various parameters that control the scanning process.

The first image Base64 string - String: image that represents one side of the document. If the document contains two sides and the ScanningMode is set to automatic, this should contain the image of the front side of the document. In case the ScanningMode is set to single, it can be either the front or the back side of the document. If the document contains only one side (for example, various passports), the SDK will automatically detect it, and will not look for the other side.

The optional second image Base64 string - String: needed if the information from back side of the document is required and the ScanningMode is set to automatic.

• The implementation of the performDirectApiScan method can be viewed here in the blinkid_flutter_method_channel.dart file.
• All of the mentioned settings can be found in the blinkid_settings.dart file.

BlinkID result

• Both methods return the BlinkIdScanningResult object, which contains the results of scanning a document, including the extracted data and images from the document.

• All of the available results can be viewed here.

Implementation guide

• A detailed guide about the integration and usage of the plugin can be viewed here.
• The sample application which demonstrates the usage of the SDK can be found in the main.dart file.

5.7.0

Plugin changes

• We changed the way BlinkID plugin is registered in Android so it no longer requires changing MainActivity. This fixes Issue #2 and Issue #5.

New features

• We translated complete SDK to the following additional languages: Malay, Dutch, Hungarian, Slovenian, Indonesian, Arabic(UAE), Romanian, Chinese traditional, Chinese simplified, Thai, Hebrew, Vietnamese, Filipino.

Improvements to existing features:

• We have improved parsing of MRZ formats deviating from the ISO/IEC 7501 standard:
  • Document discriminator was in place of the document number on driver licenses and IDs from:
    • New York
    • Michigan
    • Canada
  • Different check digit calculation for Mexico (Consular) ID
  • Recognition of the unofficial XCT country code for Northern Cyprus ID
  • Recognition of different country codes and check digit calculation on China Mainland Travel Permit for Hong Kong and Macao Residents
• We added anonymization support for:
  • MRZ on the Mainland Travel Permit for Hong Kong and Macao Residents
• We have made some changes to the BlinkID(Combined)Recognizer
  • You can now see ProcessingStatus in the results to inspect potential processing errors, such as when barcode detection fails, a mandatory field is missing, etc.
  • You can now also see a more detailed ImageAnalysisResult showing you when:
    • Face image is detected
    • MRZ is detected
    • Barcode is detected
  • We added a RecognitionModeFilter settings group. You can toggle flags on this object to control the recognition mode of the recognizer:
    • enableMrzId lets you scan MRZ on all identity documents except visas and passports.
    • enableMrzVisa lets you scan MRZ on visa documents.
    • enableMrzPassport lets you scan MRZ on passports.
    • enablePhotoId lets you scan photo IDs. Use it to enable or disable document and face image extraction on unsupported documents.
    • enableFullRecognition lets you scan all data from our supported documents.
    • Your license key still controls which of the above recognition modes are allowed.
  • We have added a RecognitionMode result member describing which recognition mode was used to produce the results.
  • We are now retrieving sex and nationality fields from the MRZ in cases where those two fields cannot be found in the document’s VIZ. Previously, we only used to do this for dates, name fields and document numbers.
  • We are now preserving the original string (raw data) of the dates we couldn’t parse.
• We have improved the thresholds for card detection feedback messages ("move closer" and "move farther"). This will improve the UX when scanning in landscape mode as the document can now be closer to the camera.

Minor API Changes

• We have made some changes to the BlinkIDRecognizer and BlinkIDCombinedRecognizer:
  • We renamed DocumentImageMoireStatus to ImageAnalysisDetectionStatus
  • We grouped the conditions member from the results with the DriverLicenseDetailedInfo structure
• We renamed RecogitionMode to RecognitionDebugMode in RecognizerBundle.

Bug fixes:

• We fixed an issue in default UI that was causing reticle to reappear while card flip animation was showing.

    • Protected fields are:
    • Document number on Hong Kong ID
    • MRZ on Hong Kong passports
    • Personal ID number on Netherlands DL
    • Personal ID number and MRZ on Netherlands ID
    • MRZ on Netherlands passports

      • By using anonymizationMode property, you can choose the AnonymizationMode: ImageOnly, ResultFieldsOnly, FullResult or None.
    • FullResult anonymization (both images and data) is set by default.

• We added support for new MRZ formats:

  • Guatemala ID
  • Kenya ID

Improvements to existing features:

• We updated UsdlRecognizerResult and IdBarcodeRecognizer.Result with additional address fields:
  • street, postalCode, city and jurisdiction
• We added expired (in Swift isExpired) property to BlinkIdRecognizerResult, BlinkIdCombinedRecognizerResult and IdBarcodeRecognizerResult.
  • It compares the current time on the device with the date of expiry and checks whether the document has expired or not.
• We made changes to the result structure of BlinkIdCombinedRecognizer and BlinkIdRecognizer:
  • Barcode data is now encapsulated in its own result structure: BarcodeResult.
  • Data from all OCR-ed fields, without MRZ data, is now encapsulated in a VizResult structure, representing the "Visual Inspection Zone" data. In BlinkIdCombinedRecognizer, front side data is available in its own structure (frontVizResult), back side data in its own (backVizResult), so you can now access data from each side separately.
  • The main part of the result, outside these structures, is filled according to these rules:
    • Document number is filled with data from the MRZ, if present.
    • Remaining data is then filled with barcode data.
    • Remaining data is filled from the back side's visual inspection zone (OCR data outside of MRZ).
    • Remaining data is filled from the front side's visual inspection zone.
    • Remaining data is filled with data from the MRZ.

Minor API changes:

• We moved BlinkIdRecognizerResult members colorStatus and moireStatus to the result's imageAnalysisResult (frontImageAnalysisResult and backImageAnalysisResult in BlinkIDCombinedRecognizerResult).

Bug fixes:

• We fixed US driver's license address extraction (Oregon, Mississippi, Rhode Island).
• We removed OpenGL entirely which was causing unexpected crashes.
