How QR Codes Work

QR Retweaker creates a public experience page first. The downloaded QR code opens that page, giving visitors clear context before they save, open, play, reply or continue.

Choose one clear job

Use the experience that matches the visitor action: Website, Text, Business Card, Event, Wedding, WiFi, PDF, audio, links, product information or a social hub.

Build for scanning

Choose a dark foreground, light background, enough quiet zone and a suitable error-correction level. Designer SVG gives you optional frames, shapes and centre marks.

Test before print

Scan the final QR with a phone before distributing it. Test the public details, action buttons, uploads and external destination.

What happens after a scan?

  1. The phone opens a Retweaker scan page. The page introduces the information or next action rather than sending the visitor to an unexplained destination.
  2. The visitor reviews the context. They can see an event detail, contact card, audio title, document name or public message before choosing what to do.
  3. The visitor takes one simple action. Save contact, open a link, play audio, add an event, copy WiFi details or view a file.
PNG and SVG encode the same destination.

Safe PNG is the reliable choice for standard printing. Designer SVG keeps your optional frame, colours, modules, centre mark and presentation details. Both open the same Retweaker scan page.

Use contrast and quiet space

Keep the QR dark on a light background. Do not crop its outer clear area. Larger printed codes generally scan more reliably from a distance.

Share only what is intended

Landing pages and attached uploads are public to anyone who scans. Do not publish passwords, payment information or confidential business data.

Test the final code

Use at least one phone camera and test in normal lighting. Confirm the QR page, contact download or final destination behaves as expected.

Publishing checklist

  • Confirm every link and public detail is correct.
  • Keep sensitive data off public QR pages.
  • Use high contrast and a clear quiet zone.
  • Scan-test the QR after downloading and again after printing.
