Can Google camera scan QR code?

I really want a QRCode reader that can scan QR codes without my mobile phone.

If you're developing for a different OS, then the Google Camera web site indicates that some APIs may not be available in your version of the OS, as in the case of Android 9.0.

There is no official Android support for QR code scanning through the camera app (although there are projects such as QRscanner that provide app-like functionality), but if you are already using Google Lens you can add a Lens and add the QR code scanning functionality by tapping on the Lens icon and scanning the code, or even clicking on a code and the QR code scanning capabilities will be enabled. There is a solution, developed by Google called "ZBar Reader for Scanning & Tagging".

How to scan Google QR code on phone?

The most successful QR codes are designed to be read by smartphones.

To scan QR code from Android, your phone must have a camera. If you have a Samsung Galaxy S3, there's an app that makes it easier. Just look for the QR code on any web page. When you launch the app, choose scan QR code from web. The phone will automatically bring the QR code in front of your phone's camera.

QR code scanner apps do not require root or adb. They require access to the screen. If your phone is rooted, it might be easier to manually move the image on the screen. Otherwise, you need an app that can grab the contents of your screen. You might consider using a jailbreak app such as iLauncher.

ILauncher is an app for jailbroken iPhone and iPad devices. It lets you customize the home screen to your liking and includes a "screenshot" mode. The screenshot mode captures the screen and save it as a PNG image. ILauncher can also display the QR code. The following instructions assume that you are using an iDevice with a jailbreak.

How to install iLauncher? Download the latest version of iLauncher from its website. It's free. Click on "Install". Don't install from the App Store.

How to move an image from iLauncher to the iDevice's camera? iLauncher includes the ability to capture images or videos and send them to your device's default email app. As of version 2.6, iLauncher also includes an option to display the QR code. However, if the QR code needs to be displayed over an image or video, you'll need to capture the image/video first.

In iLauncher, navigate to the "Email" tab. Select the "New Email" button.

Open the Email app. In the new email, add an attachment. Select "From Image or Video" and select the type of media (png, jpg, mp4, and m4v). Choose the image or video you want to include in the email. To display the QR code, choose "Add QR Code." A QR code image will appear in the email.

QR codes, also known as quick response codes, are 2D barcodes (which can also be called two-dimensional codes) used for identifying data and tracking products in stores and offices. They were first introduced by Toyota in 1994 to track its automobiles and now they're everywhere. Now, Google has released a free app that allows you to scan a QR code to quickly jump from the Web to any website or app.

In its description, Google says: Use Google Code Search to quickly jump from the web to any app anywhere. No more typing URLs into a browser. Just point your camera at the code on a website and launch the app.

If your business uses Google Code Search whether for your own project, or as a public repository you can use this app to jump right to a code, no matter where it's on the web, the developer writes. Whether you're working on an internal app, or just trying to save time while on the go, this is one of the easiest ways to quickly jump from the web to your app.

The Code Scanner app is available in the Google Play Store for Android users and will be coming soon to iOS. Update: If you want to get a better idea of what a QR code is, we've included a video below.
