Frequently Asked Questions (FAQ)
A. No, they do not expire. As long as the target destination URL remains active, your generated QR code will work indefinitely. However, please note that if you change or delete the destination URL itself, the QR code will no longer be able to access the content.
A. Choosing bright tones for the code or utilizing colors too close to the background color makes it difficult for devices to scan. We strongly recommend a high-contrast combination like a "white background" with a "dark code pattern". Always test scanning the QR code with your own smartphone prior to distribution or printing.
A. Yes, commercial and profit-driven usage is fully permitted without any limitations.
