What is a QR Code

A QR code, short for Quick Response code, is a two-dimensional barcode that can store various types of information. It was created in 1994 by the Japanese company Denso Wave as a way to track vehicles during manufacturing, but it quickly gained popularity in other industries due to its versatility.

A QR code consists of black squares arranged on a white background. These squares represent a binary code, which can encode alphanumeric characters, symbols, and even binary data. QR codes can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data, making them ideal for storing website URLs, contact information, Wi-Fi network credentials, and much more.

QR codes are widely used in advertisements, product packaging, event tickets, and business cards. They offer a convenient way for users to access additional information or perform certain actions quickly and easily. All you need is a smartphone with a QR code scanner app or built-in QR code reader to scan the code and extract the encoded data.

How to Scan a QR Code

To scan a QR code, you'll first need to download a QR code scanner app from the Google Play Store. There are many free options available, such as Barcode Scanner, QR Code Reader, or Google Lens. Install the app of your choice and open it.

Once you have the QR code scanner app installed, simply open the app and point your phone's camera at the QR code. The app will automatically scan the code and decode the information it contains.
