Add barcode, MRZ and VIN scanning to .NET MAUI apps on Android, iOS and Windows with one NuGet package, Plugin.Maui.Barkoder. Place a BarkoderView in XAML, handle results in C#, and test it on your own barcodes with a free 30-day trial.
barKoder is a .NET MAUI barcode scanning library published on NuGet. You add one package, place a BarkoderView in your XAML page and receive results in C#. The same package covers Android, iOS and Windows.
Build a short sample set from your real workflow:
Without a license the SDK still scans, but results come back marked (Unlicensed) and only partly readable. Request a trial key first, then compare reads, misses and time to result on your target devices. A trial license lasts 30 days and covers up to 25 devices.

The code below is copied from the .NET MAUI installation guide. It registers the handler, adds the view and starts a scan.

BKDView.SetLocationInImageResultEnabled(true);
BKDView.SetRegionOfInterestVisible(true);
// Enable desired barcode type

public class YourPage : ContentPage, IBarkoderDelegate
{
// Your existing methods and properties...
// Method to start the scanning process
private void StartScanning()
{
// Start scanning using the BarkoderView control and pass 'this' as the delegate
BKDView.StartScanning(this);
}
// Implementing the DidFinishScanning method from IBarkoderDelegate
public void DidFinishScanning(BarcodeResult[] result)
{
// Handle the scanned result here
foreach (var barcode in result)
{
// Do something with each barcode result, for example:
Console.WriteLine($"Scanned barcode: {barcode.TextualData}");
}
}
}IBarkoderDelegate isn't limited to a ContentPage. The MAUI pitfalls page shows how to use BarkoderView from a view model in an MVVM app.
Each mode is a few configuration calls on the same BarkoderView. The snippets come from the .NET MAUI examples in the barKoder docs.
Scan item after item without restarting the scanner. The duplicate threshold decides what happens with repeats: -1 reads each barcode once, 0 reads it again with no delay, and a value above 0 waits that many seconds. This is the setup to use when you need a Maui continuous scanning SDK for receiving, counting or picking.
BKDView.SetCloseSessionOnResultEnabled(false);
BKDView.SetThresholdBetweenDuplicatesScans(0); // it can take values -1, or n > 0Batch MultiScan reads several barcodes of any type at once, which makes the plugin a Maui multiscan SDK for shelves, cartons and pallets. The example keeps the session open, allows up to 200 results and sets decoding speed and resolution to Normal, as the docs recommend.
// Enabling MultiScan
BKDView.SetCloseSessionOnResultEnabled(false);
BKDView.SetMaximumResultsCount(200);
// For best result decoding speed should be normal, and barkoder resolution should be normal
BKDView.SetDecodingSpeed(Plugin.Maui.Barkoder.Enums.DecodingSpeed.Normal);
BKDView.SetBarkoderResolution(Plugin.Maui.Barkoder.Enums.BarkoderResolution.Normal);Turn the view into a Maui MRZ scanner by enabling the ID document type. It reads the machine-readable zone and returns data such as name, nationality, passport number and expiration date. MRZ results can also include images of the document, the holder's picture and the signature.
private void SetActiveBarcodeTypes()
{
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.IDDocument, true);
}A VIN can be printed in four barcode types. The Maui VIN scanning SDK setup enables all four, applies VIN restrictions and uses slow decoding at FHD resolution. With an OCR-enabled license, OCR VIN support (added in version 1.6.7) reads the printed characters when the barcode can't be decoded.
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.QR, true);
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.Datamatrix, true);
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.Code128, true);
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.Code39, true);
BKDView.SetEnableVINRestrictions(true);
BKDView.SetRegionOfInterest(0, 30, 100, 40);
BKDView.SetRegionOfInterestVisible(true);
BKDView.SetDecodingSpeed(Plugin.Maui.Barkoder.Enums.DecodingSpeed.Slow);
BKDView.SetBarkoderResolution(Plugin.Maui.Barkoder.Enums.BarkoderResolution.FHD);Direct Part Marking puts a Data Matrix code straight onto metal or plastic, without a label. As a Maui DPM barcode scanner, the plugin enables Data Matrix with DPM mode, slow decoding, FHD resolution and a small region of interest.
BKDView.SetBarcodeTypeEnabled(Plugin.Maui.Barkoder.Enums.BarcodeType.Datamatrix, true);
BKDView.SetDatamatrixDpmModeEnabled(true);
BKDView.SetDecodingSpeed(Plugin.Maui.Barkoder.Enums.DecodingSpeed.Slow);
BKDView.SetBarkoderResolution(Plugin.Maui.Barkoder.Enums.BarkoderResolution.FHD);
BKDView.SetRegionOfInterest(40, 40, 20, 10);
BKDView.SetRegionOfInterestVisible(true);Plugin.Maui.Barkoder brings the native barKoder engine to each MAUI target, so one C# codebase scans on phones, tablets and Windows devices.

ZXing.Net.MAUI is a free, MIT-licensed library, and many MAUI apps start with it. Both are installed from NuGet, so the choice comes down to what you scan and where.
magic5 moved its delivery and inventory scanning to barKoder after ZXing.NET became unreliable. Read how magic5 replaced ZXing.NET. Whichever you test, use the same samples and devices for both.
The engine behind Plugin.Maui.Barkoder also ships as native, web, desktop and cross-platform SDKs, so the same decoding runs wherever your C# app connects.

Yes. Plugin.Maui.Barkoder supports Android, iOS and Windows, and the NuGet package includes native Windows libraries for x64 and ARM64. You write the scanner once in C# and XAML and run it on all three targets.
Add Plugin.Maui.Barkoder to your project, register BarkoderViewHandler in MauiProgram.cs, add the camera permission on iOS and place a BarkoderView in your XAML page. The .NET MAUI installation guide walks through each step.
Yes, and the setup is similar: a NuGet package, a camera view and a result callback. ZXing.Net.MAUI is free and open source. barKoder is a commercial SDK built for damaged, blurred and engraved barcodes, MRZ and VIN scanning, Batch MultiScan and Windows camera scanning. Test both on your own samples, then check barKoder pricing.
Yes. Enable the IDDocument barcode type to read the machine-readable zone of passports, ID cards and visas. The MRZ example for .NET MAUI also shows how to read the document, picture and signature images from the result. For field mapping, see the MRZ parser.
Only for the license check. The SDK checks the license key with the barKoder licensing server when the app initializes it. All scanning runs on the device, and each device must reach the licensing server at least once every 30 days to keep returning licensed results.
Yes. Any class can implement IBarkoderDelegate, so a view model can start scanning and receive results. Pass the BarkoderView to it, as shown in the MAUI pitfalls page.
Yes. Pass a base64 image string to ScanImage to decode BMP, PNG or JPG files. See gallery scan for .NET MAUI.
Get a key on the trial page or in the barKoder portal. A trial license lasts 30 days and can be deployed to up to 25 devices, and it is meant for development and staging. Without a license the SDK still scans, but results come back marked (Unlicensed) and only partly readable.
Install Plugin.Maui.Barkoder and test it on your own barcodes and devices with a free 30-day trial, or talk to an SDK expert about your project.
