How to Decode QR codes?

Download a QR code scanning app: First, if you don't already have one, download a QR code scanning app from your device's app store. There are many free options available for both iOS and Android devices.
Open the QR code scanning app: Launch the QR code scanning app on your smartphone.
Position the QR code: Hold your smartphone steady and position the camera so that the QR code is within the viewfinder of the app. Make sure the QR code is well-lit and not obstructed.
Scan the QR code: Once the QR code is in focus, the scanning app will automatically detect it and decode the information embedded within it. You may need to tap the screen to initiate the scanning process in some apps.
View the decoded information: After successfully scanning the QR code, the app will display the decoded information on your smartphone screen. This could be a website link, text, contact information, or any other type of data encoded within the QR code.
Take action: Depending on the type of information decoded from the QR code, you can take appropriate action. For example, if it's a website link, you can choose to open it in your web browser. If it's contact information, you may have the option to save it to your contacts.
Optional: Some QR code scanning apps may offer additional features, such as saving scanned history, sharing decoded information, or integrating with other apps on your device.

How Does It Work?

Image Capture: The first step is capturing an image of the QR code using a camera-equipped device, such as a smartphone or a webcam. The camera captures the QR code as a two-dimensional array of black and white squares.
Detection and Localization: Once the image is captured, the QR code decoder software analyzes it to detect and localize the QR code within the image. This involves identifying the three square alignment patterns that are present in all QR codes, which help the decoder determine the orientation, size, and position of the code.
Image Preprocessing: Before the actual decoding process begins, the captured image may undergo preprocessing steps to enhance its quality and improve the accuracy of decoding. This may include adjusting brightness and contrast, removing noise, and sharpening edges.
Grid Division: The QR code is divided into a grid of modules, with each module representing a black or white square in the QR code pattern. The grid division allows the decoder to analyze the individual modules and interpret the encoded data.
Data Extraction: The decoder then examines the arrangement of black and white modules within the QR code grid to extract the encoded information. This involves interpreting the patterns of squares according to the QR code specification, which defines how data is encoded within the code.
Error Correction: Many QR codes incorporate error correction techniques, such as Reed-Solomon error correction, to ensure reliable decoding even if the code is partially obscured or damaged. The decoder uses these error correction codes to identify and correct errors in the encoded data.
Decoding: Finally, the decoder translates the sequence of modules into the encoded data. This data could include text, URLs, contact information, or other types of information depending on what was encoded in the QR code. The decoded information is then made available to the user through the QR code scanning application.
