How to scan a QR code



As smartphones become more and more ubiquitous, so are QR codes. These maze-looking squares are a kind of matrix barcode that contains data – usually QR codes refer to a website or open a designated application.

Although they may look confusing, QR codes are ridiculously easy to use. Follow the steps below to turn your phone into an instant QR code scanner with nothing more than your standard camera app.

How to scan a QR code on an iPhone

Step 1

: Open the camera app. Apple's iPhones have built-in functions for scanning QR codes, so there is no need to download a separate scanning app unless you really want to. Since iOS 12, there is even a direct QR code reader in the Control Panel.

Step 2: Position your telephone so that the QR code appears in the digital viewfinder. The camera app must automatically recognize the QR code. The correct distance and angle can of course help. The QR code does not have to fill the entire screen, but all four corners must be visible. If your camera is skewed, the app may have problems recognizing the code, so a direct approach is best. Image stabilization technology helps a lot with the shaking, but try to move too much so that the code square remains visible.

Step 3: Start the code. Your iPhone will not automatically initiate the QR code activity. Instead, a notification bar appears at the top of the screen indicating that the QR is understood, usually with a handy brief description of what the QR code will do – such as opening a specific web page. If you think the QR code is safe, tap the notification bar to start the code activity.

Step 1: Check if your Android phone supports scanning QR codes. Not all Android phones have this capability, so you may need to take some extra steps before scanning. Google Assistant can detect QR codes. Simply press and hold the Home icon or say & # 39; OK, Google & # 39; and then tap the Google Lens icon in the lower right. If you have a Samsung phone with Bixby capabilities, Bixby can also automatically detect QR codes. Otherwise you may have to add an app. We recommend downloading the QR code reader, which is a simple and very effective option (albeit with advertisements), or the slightly more complex i-nigma Barcode Scanner.

Step 2: Open your scan app. Open the app, whether it is Bixby, QR code reader, Samsung optical reader or any option installed on your Android phone. These apps must have a & # 39; scan & # 39; function that you can choose directly, or which is opened directly through the camera to a scan window.

Step 3: Insert the QR code. Remember that the corners of the code must be fully visible in the scan window and that the camera is more or less directly above the code to work. Hold the phone still while it identifies the code.

Step 4: Select the correct option. The app must then provide a pop-up option to perform an action based on the QR code. You may be asked if you want to navigate to a website, download something, or open an app that you are currently using. If you trust the source, think the QR code is safe and understand what it will do, select the most suitable option for you.
