Frequently Asked Questions
- How does the built-in QR Code generator operate?
- Text and URLs are encoded client-side with error-correction level M as a minimum; the library may raise it when the stronger level fits the same symbol. Content beyond the encodable capacity is rejected with a message.
- Are messages stored on external database servers?
- No. State remains strictly within the local browser memory session.
Technical Methodology & Display Science
Typography scales with the viewport. Check the message at the real venue because distance, acuity, glare, character size and contrast affect legibility.
QR content is encoded locally with error-correction level M as a minimum, optional automatic boosting when capacity permits, and a four-module quiet zone. The interface rejects content whose encoded representation exceeds supported capacity.
Themes offer contrast options; check legibility for the chosen colors and text size. There is no claim of comprehensive WCAG AAA certification.
