Hi there!
Based on your search criteria it seems that you want to learn how would the Personal Identifier look in real action. Once configured this is easily visible in different Check-In methods. This article covers what a visitor experiences when a question is flagged as a Personal Identifier — on a lobby kiosk, and through a mobile check-in QR scan.
Nothing has to be switched on at the kiosk or on the mobile template. The rule follows the published workflow, so wherever that workflow is used to create a visit, the duplicate check applies.
What a visitor sees on a kiosk
- The visitor taps to start a check-in and reaches the questionnaire.
-
They fill in the identifier question along with the rest of the form — most commonly Phone.
- They tap Continue.
-
If the value is not already in the queue, the check-in completes and the visitor is issued a ticket as normal.
-
If the value is already on an active visit, the kiosk refuses the check-in and shows a message telling the visitor they are already in the queue. The form stays open so the value can be corrected.
- They will need to go back and update their phone number to proceed to queue.
Note: The kiosk does not tell the visitor which ticket they already hold, or what position they are in. If they have genuinely forgotten, they need to ask a member of staff, who can find the existing ticket by searching the same value in the Queue.
What a visitor sees on mobile
The mobile check-in link runs the same workflow in the visitor's phone browser, so the sequence is identical.
- The visitor opens the link — from a QR code in the lobby, a link you have sent them, or your website.
- They complete the questionnaire, including the identifier question.
- They tap Continue.
- A unique value completes the check-in and the visitor sees their ticket and position.
- A value already in the queue is refused with the same message as the kiosk.
Kiosk and mobile compared
| Consideration | Kiosk | Mobile |
|---|---|---|
| Who is standing there | A shared device. The next visitor in line may be the one who hits the message, having typed a number that a relative used minutes earlier. | The visitor's own device, so a duplicate is almost always the same person checking in twice. |
| Most common cause of an unexpected block | Two people arriving together and giving the same household or mobile number. | The visitor tapped the link twice, or re-opened it after their first check-in. |
| What the visitor does next | Asks a member of staff, who is standing nearby. | Has no staff member in front of them, so they may simply give up and leave. |
| Practical advice | Brief lobby staff to expect the message and to look up the existing ticket rather than re-checking the visitor in. | Use a Field description or Field Tooltip on the identifier question that tells the visitor what to do if they are told they are already in the queue. |
Troubleshooting
| Symptom | Likely cause |
|---|---|
| A visitor is blocked but insists they have not checked in | Someone in their party used the same number, or their previous visit today is still open. Search the value in the Queue and check Today's Visits. |
| The same person got two tickets from the kiosk | They typed the value differently the second time, or the question was left blank. A blank answer cannot be matched. Make the question Required and prefer SMS-Enabled Phone over free Text. |
| Duplicates are getting through on mobile but not the kiosk | The two templates are probably connected to different workflows. Check the workflow attached to each template and confirm the identifier is flagged in both. |
| Nobody is ever blocked | The workflow was not published after the checkbox was selected, or the question is not Customer Facing so the visitor never answers it. |
| Legitimate visitors are being turned away in groups | Your identifier is shared between people. Pair it with a second identifier — see How to Configure the Personal Identifier on Questions, which explains that all flagged answers must match before a check-in is blocked. |
Notes
- The rule only applies to active visits. Once a visit is served, cancelled, or marked as a no-show, the visitor can check in again from either surface.
- A blank answer is never treated as a duplicate.
- The Personal Identifier is not identity verification. It confirms only that the same value is not already waiting.
- Test both surfaces after publishing. Check in once from the kiosk, then try the same value on the mobile link and confirm you are blocked — that also proves both templates are on the same workflow.
