What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can store various types of information such as text, URLs, contact details, and more. QR codes can be quickly scanned by smartphones and other devices with cameras to instantly access the encoded information.
What are the benefits of using QR codes?
- Quick and easy access to information without typing
- Contactless sharing of data, perfect for hygiene-conscious environments
- Can store large amounts of data in a small space
- Works offline once generated
- Cost-effective marketing and information sharing tool
- Trackable for analytics and engagement metrics
How do I read/scan QR codes?
Most modern smartphones can scan QR codes using their built-in camera app. Simply open your camera, point it at the QR code, and tap the notification that appears. Alternatively, you can download dedicated QR code scanner apps from your device's app store.
What types of information can QR codes store?
- Website URLs and links
- Plain text and messages
- Contact information (vCard format)
- WiFi network credentials
- Email addresses and pre-composed emails
- Phone numbers for quick dialing
- SMS messages with pre-filled text
- Geographic coordinates and locations
Are QR codes secure?
QR codes themselves are not inherently secure or insecure - they're simply a way to encode information. The security depends on what the QR code contains and where it leads. Always be cautious when scanning QR codes from unknown sources, as they could potentially lead to malicious websites or download harmful content.
Can I customize the appearance of QR codes?
Yes! QR codes can be customized with different colors, logos, and designs while maintaining their functionality. Our generator allows you to add logos to the center of your QR codes. You can also adjust the error correction level to ensure the code remains scannable even with customizations.
What is error correction in QR codes?
Error correction allows QR codes to remain readable even if they're partially damaged or obscured. Higher error correction levels (like High 30%) can recover from more damage but result in denser codes. Lower levels (like Low 7%) create simpler codes but are less resilient to damage.
Do QR codes expire?
Static QR codes (like the ones generated here) do not expire - they will work indefinitely as long as the encoded information remains valid. However, if a QR code links to a website, the code will stop working if the website goes offline or the URL changes.
