Actualizado:julio 28, 2025

QR Code (Quick Response Code) can instantly connect your mobile devices to websites, forms, and digital content. With Google's services integrating QR code functionality directly into their ecosystem, scanning and creating QR codes has never been easier. Whether you're a business owner looking to enhance customer feedback collection, a professional seeking efficient ways to share contact information, or someone interested in personal use of QR codes, this guide covers everything you need to know about working with Google QR codes. We'll also introduce the IronQR library as a programmatic solution for integrating QR code capabilities into the application.

Scanning QR Codes with Google App

The Google app offers a built-in QR code scanner. The process is straightforward, whether you're scanning QR codes from product packaging, accessing an online survey, or collecting feedback through Google Forms. The scanner works on most mobile devices and requires only a working camera and an internet connection for full functionality.

For instance, if you encounter a QR code on product packaging or need to submit customer feedback, you can point your camera at the code to access the encoded information. The scanner automatically detects the code and provides immediate access to websites, contact information, or Google forms without manual URL entry. Before scanning QR codes with your Google app, ensure you have the latest version installed on your smartphone.

How to Scan QR Codes: Step-by-Step Guide

Launch the Google app on your smartphone and locate the camera icon in the search bar at the top of your screen.
Tap the camera icon to activate the QR code scanner feature. If prompted, grant the app permission to access your camera.

Position your phone so the QR code appears clearly in the viewfinder. The app will automatically detect the two-dimensional barcode.
Hold your device steady while the scanner processes the code. Ensure you have adequate lighting and a clear view of the entire code.
Once scanned, tap the notification that appears to access the encoded content, whether it's a website, contact information, or Google form.

When working correctly, the scanning process is seamless and takes just a few seconds. As soon as the QR code is detected, the Google app automatically processes the information and displays the relevant content on your screen.

Creating QR Codes with Online Generator

The QR Code Generator platform offers a user-friendly interface that lets you create a custom QR code for various purposes, from simple links to complex dynamic codes that can be edited even after printing.

When you generate QR codes online, you have the flexibility to encode different types of data. You can create a QR code for your profile picture, link to Google forms for collecting feedback, display contact information, or direct users to specific URLs. This website supports both static and dynamic QR codes. It gives you the ability to track QR code scans and modify the encoded content without creating a new code.

How to Create QR Codes: Step-by-Step Guide

Visit qr-code-generator.com and select your desired content type from the available options (URL, vCard, Text, Email, SMS, WiFi, etc.).
Enter your content in the text field or upload your file in the designated area. The QR code will be generated automatically as you type or upload.
Click the "Frame" option to choose from various frame designs, then use "Shape & Color" to customize the QR code's appearance.
Add your logo if desired by clicking the "Logo" option and uploading your image file.
Click the "Download" button to save your generated QR code in JPG format, or select "Print Quality" for high-resolution SVG files suitable for printing. If you sign up, you can store the generated QR codes in your profile.

```
Install-Package IronQR
```

Add the following code to your project to generate a basic QR code:

using IronQr;
using IronSoftware.Drawing;

// Set the license key for IronQR (if applicable)
License.LicenseKey = "License-Key";

// Create a new QR code with the specified URL
QrCode mainQrCode = QrWriter.Write("https://ironsoftware.com/csharp/qr/");

// Convert the QR code to an image
AnyBitmap qrCodeImage = mainQrCode.Save();

// Save the QR code image to a file
qrCodeImage.SaveAs("feedback-form-qr.png");

using IronQr;
using IronSoftware.Drawing;

// Set the license key for IronQR (if applicable)
License.LicenseKey = "License-Key";

// Create a new QR code with the specified URL
QrCode mainQrCode = QrWriter.Write("https://ironsoftware.com/csharp/qr/");

// Convert the QR code to an image
AnyBitmap qrCodeImage = mainQrCode.Save();

// Save the QR code image to a file
qrCodeImage.SaveAs("feedback-form-qr.png");

Imports IronQr
Imports IronSoftware.Drawing

' Set the license key for IronQR (if applicable)
License.LicenseKey = "License-Key"

' Create a new QR code with the specified URL
Dim mainQrCode As QrCode = QrWriter.Write("https://ironsoftware.com/csharp/qr/")

' Convert the QR code to an image
Dim qrCodeImage As AnyBitmap = mainQrCode.Save()

' Save the QR code image to a file
qrCodeImage.SaveAs("feedback-form-qr.png")

$vbLabelText $csharpLabel

Customize the code by replacing "https://ironsoftware.com/csharp/qr/" with your desired content (URLs, text messages, or contact data).
Run your application to generate the QR code file.
