How QR Code Works?

QR codes, short for Quick Response codes, are two-dimensional barcodes that store information in a grid of black and white squares. These codes are available to scan using a smartphone or other QR code reader devices. Then, the encoded data is translated into readable information such as URLs, text, or contact details. Here’s a brief overview of how QR codes work:

1. The code is converted into a binary format and then represented by the pattern of squares in the QR code.

2. When you scan a QR code with your phone, the device’s software reads the pattern of squares and decodes the binary data back into its original form.

3. QR codes have built-in error correction capabilities. These allow them to scan the code even if they are partially damaged or obscured.

4. Once the QR code is successfully scanned and decoded, the information is displayed on your device. For example, if the QR code contains a URL, your phone will prompt you to open the link in a web browser.
