Frequently Asked Questions
What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that stores information as a series of pixels in a square grid. It can be easily read by digital devices like smartphones.
How do QR codes work?
QR codes encode information in a pattern of black and white squares. When scanned by a device (like a smartphone camera), the pattern is decoded into usable data, such as a URL, text, or contact information.
What can QR codes be used for?
QR codes are versatile and can be used to share website links, Wi-Fi network details, contact information (vCards), plain text, event details, app download links, and much more.
Are QR codes safe to scan?
Generally, yes. However, be cautious when scanning QR codes from unknown or untrusted sources, as they could potentially lead to malicious websites. Always verify the source if possible.
Do QR codes expire?
The QR code image itself does not expire. However, the information it links to (e.g., a website URL for a promotion) can expire or become inactive if the linked content is removed or changed.
What's the difference between static and dynamic QR codes?
Static QR codes have their data directly encoded into the pattern and cannot be changed once generated. Dynamic QR codes link to an intermediary URL that can be updated, allowing the destination content to be changed without altering the QR code itself. This generator creates static QR codes.
