Your whole screen network at a glance
See what every screen is showing, which ones are online, and what is playing next. Live screenshots come straight from the screen, not from a guess.
Digital signage for branch networks
Every branch screen, on rate and on time.
Cosigna runs exchange-rate boards, tickers, promotions and live TV on every screen in every branch, from one dashboard on your own servers. When the network drops, screens keep playing.

Features
One dashboard for every screen you own.
Content, schedules and live data are managed centrally and delivered to each screen ahead of time.
Rates boards that never drift
Publish FX, deposit or loan rates once. Every table and ticker that shows them updates within seconds, with flags, trend arrows and "as at" times added automatically.

Campaigns on a schedule
Run a savings promotion weekday mornings in coastal branches and a loans campaign on weekends everywhere. Dayparts, date ranges and priorities, previewed on a week timeline.
Design layouts without a designer
Start from a template or a blank canvas. Drag zones, snap to guides, bind a table to a feed, and see the real data while you work.
Live TV and streams
Show a news channel or an in-house stream beside your rates. If the source drops, a fallback image takes over and the stream returns by itself.

Alerts before customers notice
Get told when a screen goes offline, a rate feed goes stale or a stream is down, by email or webhook.
Proof of play
Reports show what played where and for how long, per screen, per campaign, exported to CSV for marketing and audit.

Rates are indicative and subject to change.
Built for banks
The rate on the screen is the rate at the counter.
- Exact decimals, end to endRates travel as exact decimal values from your core system to the screen. No rounding surprises.
- Four-eyes approvalRequire a second person to approve each new set of rates before it goes live. Every version is kept.
- Stale rates are never shown as currentSet how old a rate may get. After that, screens grey it out or replace it with your notice.
- Straight from your systemsPush rates from treasury or core banking with signed API keys, or upload a spreadsheet.
Offline first
Branch links fail. Your screens don't go blank.
Each screen keeps a verified copy of everything it needs for the week ahead, and plays from it whether or not the network is there.
Publish
Marketing schedules a campaign; treasury publishes the morning's rates.
Deliver
Screens are told at once and download only what changed, resuming if a connection breaks.
Verify
Every file is checked against its fingerprint before use, then switched in all at once.
Play
The screen plays from its own copy. If the link drops, it keeps going and reports back later.
Proof of play is never lost. Plays recorded while offline are uploaded when the screen reconnects, counted once.
