QR codes are everywhere, from store windows and restaurant tables to business cards and digital invoices. You may have noticed those pixelated containers popping up in the entirety these days, but have you ever actually used one? If you’ve ever paused and wondered how to scan a QR code, you’re in the right place. In this guide, we’ll explain everything you need to know to scan QR codes confidently, whether using a smartphone or a desktop. We’ll also show you how to quickly create QR codes with URL QR Code Generator, an easy-to-use and efficient tool for individuals and businesses.
What is a QR Code and Why Are They So Popular?
A QR code, short for “Quick Response” code, is a modern evolution of the traditional barcode. Invented in the 1990s, QR codes can save a lot of extra information and are readable from multiple directions. When scanned, they perform actions like opening a URL, displaying a PDF, starting an email draft, or connecting to Wi-Fi.
The rise in contactless technology, especially at some stage in the pandemic, pushed QR codes into the spotlight. They’re now widely utilized in:
- Retail checkout counters
- Restaurant menus
- Digital payment
- Event ticketing
- Healthcare forms
- Business marketing material
As these codes simplify how we access digital content, learning how to use a QR code becomes vital for modern digital interaction.
Devices You Can Use to Scan QR Codes
Almost all smartphones and tablets today have QR code scanning capabilities. In a few instances, scanning is incorporated directly into the camera. You may need a separate app like Google Lens or a QR reader.
Here’s the way to get started, based on your device type.

Apple made it easy for users to interact with QR codes.
To scan a QR code on an iPhone:

- Tap the Notification Banner: Once your iPhone detects the QR code, a banner with the action (usually a link) appears at the top. Tap it to proceed.
Note: This function is available on iOS 11 and later. If it’s not operating now, check that “Scan QR Codes” is enabled in Settings > Camera.
