Frequently Asked Questions (FAQ)
What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can store various types of information, such as URLs, text, contact details, or Wi-Fi credentials. They can be easily scanned using smartphone cameras and are widely used for marketing, payments, information sharing, and more.
What is Error Correction Level?
QR codes have built-in error correction to ensure they can still be read even if partially damaged or obscured. Higher error correction levels (like H) allow more of the code to be damaged but increase the density (complexity) of the QR code pattern.
- L (Low): Recovers ~7% of data.
- M (Medium): Recovers ~15% of data.
- Q (Quartile): Recovers ~25% of data.
- H (High): Recovers ~30% of data.
What can I encode in a QR code?
QR codes can encode various types of information:
- Website URLs
- Plain text
- Contact information (vCard)
- Wi-Fi network credentials
- Email addresses
- Phone numbers
- SMS messages
- Geographic locations
Is there a limit to how much data a QR code can contain?
Yes, QR codes have capacity limits depending on the type of data and error correction level:
- Numeric only: Up to 7,089 characters
- Alphanumeric: Up to 4,296 characters
- Binary/Byte: Up to 2,953 bytes
- Kanji/Kana: Up to 1,817 characters
However, for practical scanning, it's recommended to keep content concise, as denser QR codes can be harder to scan.
Are QR codes secure?
QR codes themselves are not inherently secure or insecure - they simply store data. Our generator creates QR codes entirely in your browser, so your data never leaves your device. However, when scanning QR codes from unknown sources, exercise caution as they could lead to malicious websites or trigger unwanted actions.
How do I scan a QR code?
Most modern smartphones can scan QR codes directly using the built-in camera app. Simply open your camera, point it at the QR code, and a notification should appear. Some devices may require a dedicated QR code scanner app, which can be downloaded from your app store.
