Why today's numbers aren't shown yet
You scanned your new QR code, opened Analytics, and it says "No scans in this period" or shows 0. This is normal.
QRForge records every scan straight away. But most numbers on the Analytics page, the Dashboard and the trail Funnel are calculated once a night. Today's scans are added to them in the next nightly update, so they show up tomorrow. A few charts update within minutes (see Some charts update within minutes).
Your QR code works the whole time. Only the reports wait for the update.
When does the update run?
Every night. The Analytics page and the Dashboard update shortly after 01:00 UTC, and the trail Funnel shortly after 02:15 UTC. In Central Europe that is between about 02:00 and 04:15 in the morning, depending on summer time.
The update covers the previous full day (in UTC). Scans from late in the evening in your timezone may belong to the next UTC day.
Why not live?
Calculating the numbers once a day keeps the reports fast and consistent, even for codes with many thousands of scans.
Some charts update within minutes
A few parts of the Analytics page read each scan directly. They usually include a new scan within a few minutes:
- Countries, Devices and Referrers, and the Top Country number;
- the Hourly Profile and the Peak Hour number;
- Compare to the previous period;
- Total Scans, Scan Trend and Success Rate, but only while a Country, Device or Source filter is on.
Without a filter, Total Scans, Scan Trend and Success Rate wait for the nightly update, and so does the Dashboard's Top QR Codes. So for a short time, numbers on the same page may not match. After the next nightly update they agree again.
How to test a new QR code today
You do not need analytics to check that a code works:
- Scan the code with your phone camera.
- Check that the right page opens.
- Try a second phone if you can.
If the page opens, the scan was recorded. It shows in Countries, Devices and the Hourly Profile within a few minutes, and in Total Scans and Scan Trend after the next nightly update.
What this applies to
| Report | Updated |
|---|---|
| Analytics page: Total Scans, Scan Trend, Success Rate (no filter) | Nightly |
| Analytics page: Countries, Devices, Referrers, Hourly Profile, period comparison, and any filtered view | Within minutes |
| Dashboard — Top QR Codes | Nightly |
| Trail Funnel | Nightly |
| CSV export | Uses the nightly numbers |
| Google Analytics 4 (if connected) | Each scan is sent straight away |
Troubleshooting
I scanned yesterday and still see nothing
- Check the Date range includes yesterday.
- Clear any Country, Device or Source filters.
- Check you selected the right project and QR code.
- If the code's page did not open when you scanned, the scan may have been blocked: for example, the code is archived. See Archive and restore QR codes.
The numbers are still missing after two days Contact support with the name of the QR code and the date you scanned it.
