Wear Codes turns your smartwatch into an efficient QR code scanner companion. It displays multiple QR codes and barcodes including loyalty cards, payment codes, boarding passes, and contact information. Users can manage their barcode collection through the mobile phone app, which then synchronizes with their Wear OS smartwatch for easy access.

The brilliance of Wear Codes lies in its simplicity. The main screen presents a clear viewfinder that works smoothly with your watch's built-in camera. There's no clutter, no confusion - just print, scan, and go.

You can manage your codes very easily with Wear Codes. The intuitive interface allows you to add, organize, and access your codes effortlessly. This means that whether you're at a coffee shop, boarding a flight, or sharing your contact information, everything you need is just a tap away. It supports a wide array of code types, including barcodes and QR codes, catering to diverse user needs.

Getting Started with Wear Codes

Getting Wear Codes onto your watch takes small steps:

  1. Head to the Play Store on your device and download the app.
  2. Grant camera access when prompted.
  3. The app welcomes you with a clean, focused interface to request connections - its prominent scan button and logo beckon you to capture your first QR code image.
  4. Point your watch at any QR code, and Wear Codes spring into action. The viewfinder helps you align the code perfectly, while haptic feedback confirms successful scans.
  5. Each code type triggers a specific response - web links preview before opening, updated location shows immediate navigation options for restaurants, and contact details save directly to your watch while sending a message to connect.

This app can handle various QR formats. Restaurant menu codes launch straight into digital menus, while event tickets display essential details front and center. Your scan history stays organized and accessible, ready for quick reference whenever needed.

Supported Formats

Wear Codes supports an extensive range of barcode formats:

  • QR Codes
  • UPCA Barcode (US)
  • EAN13 Barcode (EU)
  • Code 128 Barcode
  • Code 39 Barcode
  • ITF Barcode
  • Codabar
  • Aztec

IronQR is a robust C# library designed to simplify the creation and reading of QR codes within .NET applications. It offers a user-friendly API to integrate QR code functionality seamlessly into .NET projects. IronQR supports various .NET versions, including .NET 8, 7, 6, Core, Standard, and Framework.

Smartwatches, with their compact form factor and integrated cameras, are well-suited for quick QR code scanning tasks. By leveraging IronQR, developers can create applications that allow smartwatches to scan QR codes efficiently, facilitating tasks such as contactless payments, event check-ins, and access control.

Code Example

To implement QR code scanning using IronQR in a C# application, install the IronQR package into your project:

Install-Package IronQR

Import the IronQR library and use the QrReader object for scanning the QR code:

using IronQr;
using IronSoftware.Drawing;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        // Set your license key
        License.LicenseKey = "Your-License";

        // Load the QR code image from a file
        var inputBmp = AnyBitmap.FromFile("QR img.png");

        // Create a QrImageInput object using the loaded image
        QrImageInput imageInput = new QrImageInput(inputBmp);

        // Initialize the QR reader
        QrReader reader = new QrReader();

        // Read the QR code from the image input
        IEnumerable<QrResult> results = reader.Read(imageInput);

        // Iterate over each result and display the decoded information
        foreach (var result in results)
        {
            Console.WriteLine($"QR Code Value: {result.Value}");
        }
    }
}
using IronQr;
using IronSoftware.Drawing;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        // Set your license key
        License.LicenseKey = "Your-License";

        // Load the QR code image from a file
        var inputBmp = AnyBitmap.FromFile("QR img.png");

        // Create a QrImageInput object using the loaded image
        QrImageInput imageInput = new QrImageInput(inputBmp);

        // Initialize the QR reader
        QrReader reader = new QrReader();

        // Read the QR code from the image input
        IEnumerable<QrResult> results = reader.Read(imageInput);

        // Iterate over each result and display the decoded information
        foreach (var result in results)
        {
            Console.WriteLine($"QR Code Value: {result.Value}");
        }
    }
}
Imports IronQr
Imports IronSoftware.Drawing
Imports System.Collections.Generic

Friend Class Program
	Shared Sub Main()
		' Set your license key
		License.LicenseKey = "Your-License"

		' Load the QR code image from a file
		Dim inputBmp = AnyBitmap.FromFile("QR img.png")

		' Create a QrImageInput object using the loaded image
		Dim imageInput As New QrImageInput(inputBmp)

		' Initialize the QR reader
		Dim reader As New QrReader()

		' Read the QR code from the image input
		Dim results As IEnumerable(Of QrResult) = reader.Read(imageInput)

		' Iterate over each result and display the decoded information
		For Each result In results
			Console.WriteLine($"QR Code Value: {result.Value}")
		Next result
	End Sub
End Class
