Verification status containing the result of the verification

AamvaBarcodeVerifier

class AamvaBarcodeVerifier

Added in version 6.19.0

Validates the authenticity of the document by scanning the barcode on the back. This verifier supports documents that follow the Driver License/Identification Card specification by the American Association of Motor Vehicle Administrators (AAMVA). It requires either the full (i.e. front & back) scanning mode or a single-sided scan of the back of the document. Start with creating a capture context and the verifier:

var dataCaptureContext = DataCaptureContext.forLicenseKey("-- ENTER YOUR SCANDIT LICENSE KEY HERE --");
var barcodeVerifier = await AamvaBarcodeVerifier.create(dataCaptureContext);

Then either initialize the front & back scanning mode:

var settings = IdCaptureSettings();
settings.supportedDocuments.add(IdDocumentType.dlViz);
settings.capturedSides = CapturedSides.frontAndBack;

var idCapture = IdCapture.forContext(dataCaptureContext, settings);

Or initialize single-sided scanning of the back of the document:

var settings = IdCaptureSettings();
settings.supportedDocuments.add(IdDocumentType.aamvaBarcode);

var idCapture = IdCapture.forContext(dataCaptureContext, settings);

Once the capture is complete, trigger the verification process. This process is asynchronous and the result will be delivered once the verification has been completed:

@override
void didCaptureId(IdCapture idCapture, CapturedId capturedId) async {
  var barcode = capturedId.aamvaBarcode;
  if (barcode != null) {
    barcodeVerifier.verify(capturedId).then((result) {
      if (result.allChecksPassed) {
        // Nothing suspicious was detected.
      } else {
        // Document may be fraudulent or tampered with - proceed with caution.
      }
    }, onError: (error) {
        // Error occurred during verification
    });
  }
}
