Best Practices for QR Code Usage
To maximize the effectiveness of your QR codes, follow these professional recommendations:
1. Provide Clear Instructions
Not everyone is familiar with QR codes. Include simple text like "Scan with your smartphone camera" near the code.
2. Ensure Proper Sizing
Your QR code should be at least 2x2 cm (0.8x0.8 in) for print materials and 100x100 pixels for digital use.
3. Test Before Distribution
Always test your QR code with multiple devices and scanning apps to ensure it works correctly.
4. Consider the Scanning Environment
For outdoor use, choose high-contrast colors and durable materials that won't fade or damage easily.
Pro Tip: Dynamic QR codes allow you to change the destination URL without changing the QR code image itself. This is perfect for campaigns where you might need to update the link later.

Frequently Asked Questions
How do I scan a QR code?
Most modern smartphones can scan QR codes directly through the camera app. Simply open your camera, point it at the QR code, and tap the notification that appears. If this doesn't work, you can download a free QR code scanner app from your device's app store.
Are QR codes free to use?
Yes, QR codes are free to generate and use. The technology is in the public domain with no licensing fees. Some advanced QR code generators may charge for premium features like analytics or dynamic URL updating, but basic QR codes are completely free.
What's the difference between static and dynamic QR codes?
Static QR codes contain fixed information that can't be changed after creation. Dynamic QR codes allow you to update the destination URL or content without changing the QR code image itself. Dynamic QR codes also typically provide scan analytics.
How much data can a QR code store?
A standard QR code can store up to 3KB of data. This translates to about 3,000 alphanumeric characters or 7,000 numeric digits. For most use cases (like URLs or contact information), this is more than sufficient.
Can QR codes be customized without losing functionality?
Yes, QR codes can be customized with colors, logos, and even some artistic designs while remaining scannable. However, it's important to maintain sufficient contrast between the code and background, and ensure the quiet zone (blank space around the code) remains intact.
Are QR codes secure?
QR codes themselves don't contain malware, but they can link to malicious websites. Always check the URL preview before visiting a site from a QR code, especially from untrusted sources. For sensitive applications, consider using QR codes with encryption or digital signatures.
How long do QR codes last?
QR codes don't expire unless the content they link to is removed or changed (for static codes). Printed QR codes will last as long as the material they're printed on remains legible. Digital QR codes can remain valid indefinitely as long as the destination remains active.
Can I track how many times my QR code is scanned?
With static QR codes, tracking isn't possible unless you use a URL shortener with analytics. Dynamic QR codes from premium services typically include scan analytics that show how many times, when, and where your QR code was scanned.
What's the best file format for saving QR codes?
For most uses, PNG is the best format as it provides lossless compression with transparent background support. For print materials, SVG or EPS vector formats are ideal as they can be scaled without quality loss. JPEG is not recommended due to potential compression artifacts.
Can QR codes work without internet?
QR codes containing plain text, contact information, or WiFi credentials can be scanned and used without internet. However, QR codes linking to websites or online content will require an internet connection to access that content after scanning.
