On-brand QR posters and live displays for every location

In EnaFeedback, every location in the Building, Floor, Unit and Location hierarchy gets an automatically generated, permanent 6-character code. That code identifies the location in every QR, NFC and display URL. A printed QR points to a 12-character short link on qr.enainnovation.com, which opens the visitor hub on your organization’s own server.

Renaming a location or reorganizing its modules does not change the poster. Each scan shows the hygiene rating, feedback, surveys and pages that are active for that location at that moment. When you deactivate a location, a scan shows "Location is inactive".

The template editor runs in a desktop browser. Upload a PNG, JPEG or WebP background up to 15 MB and 6000 px on the longest edge, then place up to 10 text elements and 3 QR elements on it. Tools include undo/redo, a grid, snapping, layers you can hide, lock and reorder, and duplicate.

Text elements can be custom text or automatic fields: location name, location code, unit name, unit plus location, building/floor/unit or the full building/floor/unit/location path. For each QR element you choose one of six styles, an error correction level of L, M, Q or H, and foreground and background colors. Placing your logo in the center raises error correction to H automatically.

For a single location you can download a poster PDF or a plain QR code PNG. Bulk download takes up to 100 locations at a time: with a template chosen, the ZIP contains one poster PDF per location; without one, it contains QR PNG files. When you open a new building, every poster is ready for print in one step.

Page size is calculated from the background’s pixel dimensions and the print resolution you set. There is no separate paper-size picker, so prepare the background for your target print size. Poster text can be downloaded in Turkish or English. PDFs are rendered on your organization’s own server, not on a central ENA service.

A waiting room screen, kiosk or tablet can be paired as a live display. It shows a dynamic QR, or a poster template whose QR slots are live, together with the location name and its building, floor and unit. The QR refreshes every 15 seconds and each code stays valid for 30 seconds, so a code scanned at the moment of refresh still works.

Photographing a dynamic QR to scan it elsewhere does not work, because the code expires within seconds. That is why a session opened from a display counts as verified. When you turn on "Verification required" for staff modules, cleaning and control logs are accepted only from sessions opened by an NFC tag or a live display QR. NFC verification works only in the EnaFeedback mobile app; tapping a tag without the app opens an unverified visit, like a printed QR.

To pair a screen, create a one-time registration code in the admin panel; it is valid for 10 minutes. On the screen, open the /display page on your organization’s address and enter the 10-character code, or use the join link. The screen receives a credential cookie, and the server stores only its SHA-256 hash.

The display rotates through your enabled visitor languages every 45 seconds, shifts its content slightly every two minutes to protect the panel, and keeps the screen awake. In the admin panel you see each display as Online, Offline or Disabled, with its last signal and scans over the last 30 days, and you can change its output, rotate its credential or disable it.
