Discover answers to the 10 most frequently asked questions about QR codes—how they work, safety tips, customization, and practical uses.
QR codes are everywhere—from menus to marketing campaigns—but many people still have questions about how they work and how to use them effectively. Below are 10 of the most frequently asked questions to help you understand and get the most from QR codes.
1. What is a QR code?
A QR code (Quick Response code) is a type of two-dimensional barcode that stores data. It’s often used to quickly direct users to a website, display contact information, or trigger actions like sending an email or connecting to Wi-Fi.
2. How do I scan a QR code?
Simply open the camera app on most smartphones and point it at the QR code. A pop-up will appear if it’s recognized. Some older phones may require a QR code scanner app.
3. Are QR codes safe to use?
QR codes are safe by design, but they can be misused. Avoid scanning codes from untrusted sources, and always double-check the URL that appears before clicking.
4. Can I create my own QR code?
Yes! There are many free and paid QR code generators online that let you create codes linking to websites, text, email, phone numbers, and more.
5. What can I link to with a QR code?
QR codes can link to websites, YouTube videos, social media profiles, digital business cards, PDF files, surveys, and more.
6. Do QR codes expire?
Static QR codes never expire. Dynamic QR codes—those that allow URL changes—can expire if you stop paying for the service that hosts them.
7. What’s the difference between static and dynamic QR codes?
Static QR codes contain fixed information and can’t be edited. Dynamic QR codes let you update the destination URL after printing, and often provide tracking analytics.
8. Can QR codes be customized?
Yes! QR codes can be customized with colors, shapes, and logos—as long as they remain scannable. Some tools even offer branded QR templates.
9. Do I need internet access to use a QR code?
It depends. QR codes that link to online content require internet access. However, those that contain plain text or contact info work offline.
10. Where should I place QR codes for best results?
Use QR codes on business cards, flyers, posters, packaging, signage, menus, email campaigns, or anywhere your audience can scan with ease.
