KardoSign

KardoSign turns any Android TV, tablet, or media stick into a managed digital signage screen — controlled from the Kardopal app on your phone.

WHO IT'S FOR
Restaurants, retail, hotels, clinics, offices, and any business running a TV that needs to show menus, promos, queue info, or announcements. Pair once with a 6-character code, then everything is managed remotely from the Kardopal app — no need to ever touch the screen again.

HOW IT WORKS
1. Install KardoSign on the display device (Android 7.0+).
2. On first launch, the screen shows a pairing code.
3. Open Kardopal on your phone, go to Signage → Add Device, and scan or type the code.
4. Push playlists of images, videos, or multi-zone compositions from your phone.
5. Content syncs and plays automatically. Updates land in seconds.

FEATURES
• Image and video playlists
• Multi-zone canvas compositions (banner + main, sidebar, quad, etc.)
• Time-windowed schedule rules (e.g. lunch menu 11:00–14:00 Mon–Fri)
• Date-bounded campaigns (e.g. Black Friday week)
• Live screenshot capture so you can verify what's on screen from your phone
• Fully cloud-managed — no on-site computer required
• Survives reboots and network blips; resumes from the last known playlist
• Software-decoder fallback for cheap signage hardware that doesn't have a full hardware H.264 path

REQUIREMENTS
• Android 7.0+ (API 24+)
• A Kardopal tenant account
• Internet connection on the display device
• Display in landscape orientation for best results
