+## Version 10
+- One method is to raise the value of [minResultConfidence](../api-reference/interfaces/simplified-barcode-reader-settings.md) of the `SimplifiedCaptureVisionSettings` interface of the capture vision router module.  It is set to `30` by default.
+
+- If the issue has to do with the length of the text result, you can try setting a minimum length for the barcode text(s) that are returned by the SDK. By setting the [minBarcodeTextLength](../api-reference/interfaces/simplified-barcode-reader-settings.md) property of the `SimplifiedCaptureVisionSettings` interface of the capture vision router module, the SDK can ignore results that are consistently coming out shorter than expected. It is set to `0` by default.
+
+```javascript
+  let settings = await router.getSimplifiedSettings('ReadSingleBarcode');
+  settings.barcodeSettings.minResultConfidence = 40; //setting confidence
+  settings.barcodeSettings.minBarcodeTextLength = 5; //setting barcodeTextLength

+## Version 10
+Preload `BarcodeReader` or other specified module proactively to save time on the initial decoding by skipping the module loading at the time of instance creation.

+await Dynamsoft.Core.CoreModule.loadWasm(["cvr", "dbr"]);

+```
+
+## Version 9
 No, the method is internally called when `createInstance` is called so there is no need to explicitly call it. However, if you would like to save some time during the instance creation, you can choose to manually call the method as soon as the page is loaded rather than letting it load on the instance creation. This can help avoid unnecessary waiting time when the library is invoked.

+- If you are including the library via the CDN link, then the version number should be mentioned in that reference link.

+## For version 9
 There are multiple ways to check the version currently being used -
 
 - The first way is to use the [version API](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/InitializationControl.html?ver=latest#version). Using this API in the browser console should print out the version of the library being used by the web app.

 # What is the difference between the BarcodeReader class and the BarcodeScanner class? Can they be used interchangeably?
 
 [<< Back to FAQ index](index.md)
-
+**_NOTE:_** - This  is for version 9 or lower of barcode reader sdk
 No, as each offers a different functionality than the other. The `BarcodeReader` class is used to decode static images (via one of the [decode\*](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeReader.html#decode-barcodes) methods) and does not have the ability to open the camera stream and decode barcodes directly from the video stream. 
 
 The `BarcodeScanner` class on the other hand has the ability to decode barcodes directly from a video input, but it can also capture a still image using the camera when `singleFrameMode` is toggled.

+
+`updateScanSettings` is used to update the [ScanSettings](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/interface/ScanSettings.html?ver=latest) interface. This can be used to configure settings such as ignoring duplicate reads, setting sound/vibration when a barcode is scanned. 
+
+`updateVideoSettings` is used to update the [MediaStreamConstraints](https://developer.mozilla.org/en-US/docs/Web/API/Media_Streams_API/Constraints) that define most of the video information such as width, height, and the camera facingMode (i.e. front or rear camera).
+
+`updateRuntimeSettings` is used to update the [RuntimeSettings](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/interface/RuntimeSettings.html?ver=latest) interface. It updates the runtime settings with a given object or use the string `speed`, `balance`, or `coverage` to use [our preset settings for BarcodeScanner](https://www.dynamsoft.com/barcode-reader/parameters/structure-and-interfaces-of-parameters.html?ver=latest#using-runtime-settings-templates). The default setting is `speed`.
