A Micro QR Code is a two-dimensional code. It is a more compact version of a standard QR code: a Micro QR Code can encode up to 35 numeric characters or 21 alphanumeric characters, enough to store a product ID or a short URL. In comparison, a standard QR code can contain up to 7,089 characters.

Micro QR Codes are often used in industries such as electronics, medical devices, and retail, where space-efficient labeling is essential.

Runtime Example

The following code snippet generates a Micro QR Code barcode and specifies its properties:

Form1.cs

using DevExpress.BarCodes;
using DevExpress.Drawing;
using System.Diagnostics;

// Create a Micro QR Code.
BarCode barCode = new BarCode();
barCode.Symbology = Symbology.MicroQRCode;
barCode.Text = "0123-456789";
barCode.Width = 150;
barCode.Height = 150;
barCode.Options.MicroQRCode.CompactionMode = MicroQRCodeCompactionMode.AlphaNumeric;
barCode.Options.MicroQRCode.ErrorLevel = MicroQRCodeErrorLevel.L;
// Save the barcode as an image.
barCode.Save("BarCodeImage.png", DXImageFormat.Png);
// Open the image in the default viewer.
Process.Start(new ProcessStartInfo("BarCodeImage.png") { UseShellExecute = true }); 

Form1.vb

Imports DevExpress.BarCodes
Imports DevExpress.Drawing
Imports System.Diagnostics

' Create a barcode control.
Dim barCode As New XRBarCode()
barCode.Symbology = Symbology.MicroQRCode
barCode.Text = "0123-456789"
barCode.Width = 150
barCode.Height = 150
barCode.Options.MicroQRCode.CompactionMode = MicroQRCodeCompactionMode.AlphaNumeric
barCode.Options.MicroQRCode.ErrorLevel = MicroQRCodeErrorLevel.L
' Save the barcode as an image.
barCode.Save("BarCodeImage.png", DXImageFormat.Png)
' Open the image in the default viewer.
Process.Start(New ProcessStartInfo("BarCodeImage.png") With {.UseShellExecute = True})
