Tips for a code that scans

  • Times are saved as the clock time you enter, so they show the same time wherever the person is.
  • Keep the description short: more text makes a denser code that is harder to scan.
  • Test on your phone to see how it adds the event.
  • Keep strong contrast between the dots and the background, and leave the empty border around the code.
  • Print it at least 2 cm (0.8 in) wide, and larger if people scan it from a distance.

Frequently asked questions

Does it add to Google, Apple and Outlook calendars?▼

The code holds a standard calendar event. Most phones offer to add it to their default calendar after scanning.

Which time zone is used?▼

None. The time is saved as written, so it appears at that clock time on the phone that scans it.

Does this QR code expire?▼

No. The code holds the information itself (or a plain link), so there is no server in between, no subscription and no scan limit. It works for as long as the destination exists.

Is my information uploaded?▼

No. The code is made in your browser. What you type is never sent to CalcMaster or stored.
