How to avoid incorrect barcode results?

SimplifiedBarcodeReaderSettings — a sub-parameter of SimplifiedCaptureVisionSettings — exposes the same two filtering properties across every edition of Dynamsoft Barcode Reader (Server, Web, and Mobile), under each platform’s own API reference, e.g. C++ and JavaScript:

• minResultConfidence – raise this value (default 30) to require a higher confidence before a result is returned. 50 or higher is a good starting point if you’re seeing unreliable reads.
• minBarcodeTextLength – set this to the minimum length your barcode text should be; results shorter than this are discarded. For example, if your barcode text should always be at least 10 characters long, set it to 10 so the SDK ignores shorter, likely-incorrect results.

Example (JavaScript):

let settings = await router.getSimplifiedSettings('ReadSingleBarcode');
settings.barcodeSettings.minResultConfidence = 40; //setting confidence
settings.barcodeSettings.minBarcodeTextLength = 5; //setting barcodeTextLength
await router.updateSettings('ReadSingleBarcode', settings);
