E-paper signage with nothing running to it
truink combines modern aesthetics with a truly wireless architecture: a premium scheduling and signage experience without the complexity of traditional displays.
Truly wireless
No power cabling. No network cabling. Tags run on battery and communicate over BLE 5.0, so a display can go where an electrician can’t.
Long battery life
2 to 5 years under normal usage conditions. E-paper draws power only when the image changes, not to hold it.
Paper-like display
Crystal-clear visibility with wide viewing angles and excellent readability, including in the bright, glare-heavy corridors where LCDs wash out.
Sustainable and cost-effective
Significantly lower power consumption, reduced maintenance, and a smaller environmental footprint than LCD-based schedulers.
Automation truink runs on your behalf
Capability by capability, the automation that runs without administrative intervention.
Thousands of labels, changed centrally
Shelf edges, buffet counters, ward and bed signage. The change happens once in the dashboard and propagates over BLE. No laminator, no reprint cycle, and no staff member walking the floor with a trolley.
A price changes once, in the dashboard. Every tag showing it repaints itself. Nobody walks the floor, and nothing is reprinted.
One tag, six deployment scenarios
None of these installations require power or network cabling.

Corporate room signage
Status and the day’s schedule outside every meeting room.

Ward & bed signage
Bedside information that updates centrally, never by hand.

OPD & token displays
Live queue position, counters and wait times.

Retail price tags
Shelf-edge pricing changed centrally, with no store walk.

Campus wayfinding
Directories and directions where cabling was never run.

Transit information
Battery-powered boards for platforms and stops.
