  • chipPage indicates which page of the document contains RFID chip (0 if there's no page containing). Requires Document Type recognition, otherwise 1 by default;

  • overallResult - it's a summary of all results, one of eCheckResult enumeration values. If at least one result status was negative, overall result will be negative;

  • elapsedTime indicates how much time has been required for document processing, milliseconds;

  • elapsedTimeRFID indicates how much time has been required for RFID chip processing, milliseconds;

  • morePagesAvailable indicates, if document has more pages (count) to be processed (e.g. ID card's front and back side). Requires Document Type recognition, otherwise 0 by default;

  • rfidResult - result of RFID reading process, one of eRFID_NotificationAndErrorCodes;

  • highResolution indicates, if document is needed with high resolution, false by default;

  • graphicResult - graphic results;

  • textResult - text results;

  • documentPosition - position of document blank result;

  • barcodePosition - position of found Barcode result;

  • mrzPosition - position of the MRZ area;

  • imageQualityGroup - image quality result;

  • documentType - document type result;

  • rawResult - contains results in the initial view, i.e. the raw view;

  • documentReaderNotification - notification data about reading process. Used when RFID chip is read;

  • rfidSessionData - results of work with the SDK within the context of the current communication session with electronic document;
