What is a QR Code and How Do You Create One for Free?

QR codes are those black-and-white square patterns you see on restaurant menus, product packaging, business cards, and advertisements. But how do they work, and how can you create your own for free?

What is a QR Code?

QR stands for Quick Response. A QR code is a type of barcode that stores information — typically a web URL, but it can store text, email addresses, phone numbers, WiFi credentials, and more. When you scan a QR code with your phone camera, it instantly reads the stored information and opens the relevant app or website.

Where Are QR Codes Used?

• Restaurant menus (scan to see the menu without touching it)
• Business cards (scan to save contact details)
• Product packaging (scan to see details or register warranty)
• Advertisements (scan to visit a website)
• Event tickets (scan to verify entry)
• WiFi sharing (scan to connect without typing a password)
