Setup Accura NFC

To initialize sdk on app start:

RecogEngine recogEngine = new RecogEngine();
RecogEngine.SDKModel sdkModel = recogEngine.initEngine(your activity context);

if (sdkModel.i > 0) { // if license is valid

     if (sdkModel.isMRZEnable) // RecogType.MRZ

     if (sdkModel.isBankCardEnable)  // RecogType.BANKCARD
     
     if (sdkModel.isAllBarcodeEnable) // RecogType.BARCODE

    // sdkModel.isOCREnable is true then get card list which you are selected on creating license
    if (sdkModel.isOCREnable) List<ContryModel> modelList = recogEngine.getCardList(MainActivity.this);
    if (modelList != null) { // if country & card added in license
        ContryModel contryModel = modelList.get(selected country position);
        contryModel.getCountry_id(); // getting country id
        CardModel model = contryModel.getCards().get(0/*selected card position*/); // getting card
        model.getCard_id() // getting card id
        model.getCard_name()  // getting card name

        if (cardModel.getCard_type() == 1) {
            // RecogType.PDF417
        } else if (cardModel.getCard_type() == 2) {
            // RecogType.DL_PLATE
        } else {
            // RecogType.OCR
        }
    }
}

Update filters like below.

Call this function after initialize sdk if license is valid(sdkModel.i > 0)

• Set Blur Percentage to allow blur on document

  //0 for clean document and 100 for Blurry document
  recogEngine.setBlurPercentage(Context context, int /*blurPercentage*/50);

• Set Face blur Percentage to allow blur on detected Face

  // 0 for clean face and 100 for Blurry face
  recogEngine.setFaceBlurPercentage(Context context, int /*faceBlurPercentage*/50);

• Set Glare Percentage to detect Glare on document

  // Set min and max percentage for glare
  recogEngine.setGlarePercentage(Context context, int /*minPercentage*/6, int /*maxPercentage*/98);

• Set Hologram detection to verify the hologram on the face

  // true to check hologram on face
  recogEngine.SetHologramDetection(Context context, boolean /*isDetectHologram*/true);

• Set light tolerance to detect light on document

  // 0 for full dark document and 100 for full bright document
  recogEngine.setLowLightTolerance(Context context, int /*tolerance*/30);

• Set motion threshold to detect motion on camera document

    // 1 - allows 1% motion on document and
    // 100 - it can not detect motion and allow document to scan.
    recogEngine.setMotionThreshold(Context context, int /*motionThreshold*/18);
