QR codes, short for Quick Response codes, are a type of two-dimensional barcode that stores information in a digital format. They were first used in the 1990s by Japanese auto manufacturers to track parts during production. Today, QR codes have become an essential tool in various industries and aspects of our lives.

Define the Concept

A QR code is essentially a square-shaped barcode that contains data such as URLs, text, email addresses, phone numbers, or even small files like images or videos. This digital information is encoded within the QR code’s intricate pattern of black squares on a white background.

How Does it Work?

When a user scans a QR code with their smartphone or tablet, the device reads the data stored in the code and takes the specified action. For example:

• If the QR code contains a URL, the phone will open the website.
• If it’s an email address, the default email app will be launched to send a new message.
• If it’s a text string, the content will be displayed on the screen.
