📱 What Is a QR Code?
A QR code (Quick Response code) is a type of barcode that can store information such as text, URLs, contact details, or Wi-Fi credentials. When you scan it with a smartphone camera, it instantly opens a link or performs an action — like visiting a website or connecting to Wi-Fi.
QR codes are faster and more flexible than traditional barcodes, which is why they’re now used everywhere — from restaurants and packaging to business cards and marketing campaigns.
🔍 How Do QR Codes Work?
A QR code is made up of black squares and dots arranged in a square grid on a white background. Each pattern encodes data that can be read by your phone’s camera or a QR code scanner.
When you scan it, your device:
- Detects the pattern.
- Decodes the data.
- Performs the related action — such as opening a webpage, sending an email, or showing a message.
🧠 Common Uses of QR Codes
QR codes are used across different industries for convenience and marketing. Here are a few examples:
- 🌐 Website links: Instantly direct users to your homepage or landing page.
- 📇 vCard: Share your contact details easily.
- 📧 Email: Generate a pre-filled email for customers to contact you.

- 💳 Payments: Enable easy mobile payment through apps like PayPal or Google Pay.
