Process rebuilds each transponder assignment from the Info and Transponder logs and times it, so you can see how long participants spend at the kiosk, which step is slow, and how often they give up.
An assignment, step by step
- Read card — from the card being found (
UID_FOUND) to the participant confirming their details (INFO_CONFIRMED). - Scan transponder — from confirming to a good scan (
SUCCESS). Failed scans happen here, and this is usually the longest step. - Commit assignment — from the good scan to the assignment being saved (
ASSIGNMENT_SUCCESS).
Every assignment ends one of these ways:
| Outcome | Meaning |
|---|---|
| Completed | Saved successfully. |
| Abandoned | The card was read, but the participant never confirmed their details. |
| Declined | The participant said the details were not theirs. |
| Max Attempts | Too many failed scans; the kiosk gave up. |
| Errored | The scan was good but saving the assignment failed. |
| Incomplete | Confirmed, but the log stops before any outcome — the participant walked away mid-scan, or the session ended. |
What it shows
- Summary — how many assignments were started and completed, and the median time end to end and for the scan step.
- Median seconds per step — completed assignments side by side with ones that hit Max Attempts.
- Funnel — how many assignments reached each step, and a count of each way they ended.
- Step Breakdown — the count, median and mean for each step. A mean well above the median means a few very slow assignments.
- Inside the Scan Phase — the median number of attempts before a failure, and the most common reasons scans failed.
- Assignment Elapsed Time — the time the kiosk itself measured for each completed assignment, over time, with a rolling average of the last 10. A rising line means the queue is slowing down.
Good to know
- Log times are recorded to the second, so the step times are accurate to about ±1 second — plenty for the scan step, rough for the short ones.
- The elapsed-time chart is the kiosk's own measurement, not worked out from the log times, so it can differ slightly from the step totals.
- One session can hold many assignments, or none; a card that fails and is scanned again starts a new assignment.
