MixerBox TurboScan is a QR Code Reader & QR Scanner designed for lightning-speed and versatile scanning. It can scan any QR Code or barcode, offering quick results. Its user-friendly design and lightning-fast scans make it a top choice for Android users.

Also, it allows uninterrupted scanning even in low-light conditions. Users can also track their scan history with a single tap, providing easy access to previously scanned codes. Despite its robust capabilities, the app is designed to be lightweight, minimizing its storage footprint on your device.

The use of QR Codes has grown because they provide quick access to a wide range of information. So, most of the latest Android devices come with a built-in QR scanner, making it easy for users to decode QR Codes without additional apps.

I have an android app which on local WiFi and doesn't require an internet connection so I am looking for a solution which can scan QR codes without requiring Google Play Services as no internet connection is there so I do not want to update Google Play Services. Currently, I am doing it by using Google Vision API but somehow(if possible) I want to remove this dependency.

QR Codes were initially developed to expand on the technology of Barcodes. QR Codes have better functionality because they can be scanned both horizontally and vertically, which comes from their square shape. Before smartphones existed, QR Codes were read with scanners for inventory management. Nowadays, the process is much more advanced because of smartphones. The process of scanning QR Codes enables you to read the information connected to them. This can be done either with a smartphone app or directly with your smartphone camera (for some newer models).

This depends on your type of smartphone or tablet, as well as your version of Android. In this article, we've listed the steps to scanning QR Codes without an app for Android versions 6.0-10.0. Please also see the section for directions on specific models of smartphones. For tablets, they work in the same manner as the respective version of Android. Otherwise, you can download a third-party QR Code scanning app mentioned above.

A great example is a QR code scanning app. QR codes can be found just about anywhere. These pixelated squares are used in advertisements, retail, food packaging, business cards and more. When scanning them, you get more information about a product or are directed to a website. You no longer need an app for that.

Some think of a maze when they see a QR code. And just like a maze, a QR code leads to discovery. How many calories are in those fries? Where can you buy the outfit you see in an ad? How many miles can this car travel on a gallon of gas? A quick QR code scan can resolve all these questions and more. Think of this tech as a smart barcode.

As QR codes have become more common, more manufacturers have built QR scanners directly into the default camera app. Samsung's Galaxy S22 will read them, as will the Pixel 7 Pro, but other phones -- particularly older models -- may not.

Then, point it at your QR code and the app will reveal the hidden information, be it a website link or whatever. Keep the scanner app in a location you'll remember as you'll need to use it whenever you want to scan a QR code.

QR codes provide a speedy means of sharing and receiving information, and post-Covid many businesses are now asking customers to scan QR codes to check into their venues, download their apps and place their orders.

There are hundreds of QR code scanners for Android devices in the Google Play store, but many are stuffed with ads or have dubious privacy policies. Besides, your phone should be able to scan QR codes without you needing to install an app. (But beware scam QR codes, which do exist and are easily to stick anywhere.)

Most Android phones now let you scan QR codes using the built-in camera app, to save you installing a third-party QR code reader. If your phone is running Android 9 (Pie) or later, its camera will offer this feature through integration with Google Lens.

On Samsung phones, you can activate this option in the Samsung Internet browser. Tap the three-line button in the bottom-right corner of the screen, choose Settings and select "Useful features." Switch on "QR code scanner," then tap your address bar and select "QR code icon" to add a scanning shortcut to the browser.

In Firefox for Android, you can scan a QR code simply by tapping the address bar and pressing Scan. Similarly, in the Edge app for Android, just tap the camera icon in the search box and choose Barcode.

From everything else I can find on the forum, it seems that for the equivalent to work on an Android, this has to be done using the Collect Android App. It seems that this will then scan the QR/barcode, rather than the human-readable. Does this mean that anyone going out to collect data must first download the Collect Android App from Google Play, and sign up to be a Kobo Toolbox user (i.e., username, password, e-mail address) before they can begin collecting data?

With the Enketo version, it seems all users need are the link to the form to fill out, and they can then simply start recording the data. Is there any way that someone with an android phone can fill out the QR/barcode question without having to go sign up to KoboToolbox and get the Collect Android App - even if this is scanning text instead of a code, as occurs on iPhones?

Thank you very much for this response, @Kal_Lam . I think I need to get a cheap android phone to test things out on. You finish by saying that collecting the data on Enketo/web form is the easiest, as it works well with both IOS & Android systems. Overall, I agree, but then I cannot include a field that requires the respondent to scan a QR code (or a text string), as this does not work on an Android :(.

If you set up 2-Step Verification, you can use the Google Authenticator app to generate codes. You can still generate codes without internet connection or mobile service. Learn more about 2-Step Verification.

In this blog post, we'll cover methods that don't require another phone or installing an external app to scan a QR code. These techniques rely on the built-in features of your smartphone's operating system, such as the camera app.

Using your iPhone to scan QR codes is a great way to access information, deals, and more quickly and easily. The process is simple and straightforward, and best of all, you don't need to download any extra apps.

QR stands for "Quick Response" because it can be quickly scanned with a smartphone camera, and then your phone will take you to a website, show you some information, or do something else, depending on what the QR code was programmed to do.

If you can't scan QR codes with your device, you can set up Okta Verify by using an activation link sent to your email or to the short message service (SMS) app on your device. You can also activate Okta Verify by using a secret key.

Further on, starting from bundled library 17.2.0 and unbundled library 18.3.0,a new feature called auto-zoom has been introduced to further enhance thebarcode scanning experience. With this feature enabled, the app is notified whenall barcodes within the view are too distant for decoding. As a result, the appcan effortlessly adjust the camera's zoom ratio to the recommended settingprovided by the library, ensuring optimal focus and readability. This featurewill significantly enhance the accuracy and success rate of barcode scanning,making it easier for apps to capture information precisely.

I have been using LP Authenticator without issue for some years but the last couple of times I have tried to add a new account by scanning a QR code, it doesn't scan. It looks like the camera is out of focus. There is no error message, it just doesn't do anything and no amount of tapping the screen or changing the distance from the QR code will kick it into life. I am not sure how long the problem has been there or in which version(s) of the app because I don't add new sites very often. The same QR codes that LP failed to scan worked fine in the Microsoft Authenticator.

I have seen other posts from people reporting problems scanning QR codes but mostly from 2 or more years ago so I'm sure the app has changed since then, and usually there was an accompanying error message.

I found a solution that worked for me and might work for you too. I reinstalled the app and it worked again. It's a total hassle, I know, but it was the only way I could get the QR codes to scan properly.

QR Codes (also known as Quick Response Codes) carry information that can only be decoded by QR scanners. Your smartphone and tablet can read QR codes without installing any additional software, simply point your camera at the code and you will be redirected to the information. Read on to find out more about the different ways to scan a QR code on your device.
