Inaktive, fehlende oder abgelaufene QR-Anzeigen verstehen

The public QR display requests a time-limited signed token for its configured point. Depending on the server response it may show a loading state, an inactive point message or an error instead of a valid QR.

Wozu dient diese Einstellung?

Use this when the shared screen is no longer displaying a scannable code.

Vorbereitungen

• A QR point has been created in ATS Cloud.
• You have the actual Public Link used by the screen.

Bedienelemente erklärt

Inactive

The saved point is not currently active; the display clears the QR.

Token missing / Load failed

The display could not obtain a usable token.

Refresh Countdown

Time until the next QR change.

90-second expiration

The display clears an expired token rather than displaying an unusable one.

Schritt-für-Schritt-Anleitung

1. Open the Public Link on the display browser.
2. If the screen reports Inactive, sign in to ATS Cloud → QR Code.
3. Open the matching QR point and inspect Active; enable it and Save if appropriate.
4. If the display reports a loading error, check the browser’s network reachability and the public URL.
5. Check whether the QR point has been removed or the Public Link is incorrect.
6. Allow the page to retry fetching a token; the Angular code retries after request errors.
7. Observe the countdown and verify that a new token appears after the refresh interval.
8. If a token expires while refresh fails, expect the QR to clear rather than treating the previous code as valid.

Wie geht es weiter?

The public display renders a code only when it has an active point and a usable token.

Wichtige Hinweise

• A static screenshot of a QR code cannot be used as a long-running attendance display.
• Do not confuse an employee’s failed scan with a display that lacks a current valid token.
