With the rise of smartphones and apps that can read QR codes, it might seem like you don’t need a QR code scanner app anymore. But if you’re looking to save time or just want to be sure you’re getting the most out of your QR code scanning app, there are a few things to keep in mind. First, make sure your QR code scanner app is up-to-date. Many of the newer apps include features that were only available in recent versions of the app’s software. If your QR code scanner isn’t up to date, it might not be able to read some of the newer codes that are being created. Second, use your QR code scanner app for more than just scanning codes. Many apps also include features that can help you create and share custom content with others. For example, some apps let you add text or images to a QR code and then share it with others. This can be a great way to share information or ideas with other people quickly and easily. Finally, be sure to use your QR code scanner app in a safe way. Make sure children don’t access the app without adult supervision and avoid using the app while driving or operating heavy machinery. ..
Flashlight apps have experienced a similar trajectory. What once required a third-party app from the app store is now a baked-in feature on Android and iPhone. You don’t need a flashlight app anymore, and you don’t need a QR code scanner app anymore either.

What Is a QR Code Scanner?
A QR code scanner is simply an app that can detect QR codes. A QR code is a form of barcode that contains information. You and I can’t read that information with our eyes, but a QR code scanner can.
QR codes can contain many different things. It can be a simple URL, plain text, a contact card, PDF, email, phone number, Wi-Fi network details, or even a prefilled text message. There’s a lot that can be done with QR codes, which is why you should know how to scan them.
All you have to do is point the app at the QR code and you’ll see the information contained in the strange boxy pattern. Except you don’t need an app anymore.

The Problem With QR Code Scanner Apps
The main problem with QR code scanner apps is they’re unnecessary. Both the iPhone and Android phones have built-in methods for doing this.
The iPhone’s camera app can automatically detect when a QR code is in the frame. It’s as easy as taking a photo. You can also create a shortcut to the QR code scanner in the Control Center.
The story is much the same over on Android. Samsung Galaxy phones can also scan QR codes with the camera app. If yours can’t do that, a shortcut can be added to the Quick Settings panel.
Beyond simply being redundant, QR code scanner apps have the same security and privacy concerns as flashlight apps. Many of them abuse permissions that are not necessary for scanning a QR code. It’s a sneaky way to hide malware in an otherwise unassuming app.
At the end of the day, QR code scanner apps are just a relic of the early smartphone era. Android and iOS have evolved to include features like this that make highly specialized apps unnecessary. It’s a bit of a bummer for developers who were making nice apps, but easier for you.
