TV call display for queues: how it works for clinics, restaurants and notary offices
The TV call display is the public screen for the queue — it sits on a reception monitor and shows who's waiting, who's in service, and the day's served customers in real time. On each new call, it announces the ticket number and customer name out loud for accessibility. Runs on any monitor with a browser, no special hardware or installed app.
What appears on the call display
The public screen shows two main lists: "Waiting" (customers still in the queue with numbered ticket and shortened name) and "In service" (who's being served now, with room or professional when applicable). Above the lists, live stats: total waiting, in service, served today, and average service time. When calling the next person, the called ticket is highlighted, flashes for a few seconds, and is announced by voice.
Voice call (TTS)
Each new call automatically triggers a synthesized voice that announces, for example: "Ticket 42, Diego". Audio comes through the monitor's own speakers (or the reception TV). Crucial for accessibility — helps elderly customers, visually impaired users and noisy rooms where reading the screen isn't viable. Also partially addresses Brazilian inclusion law (Law 13.146/2015) by offering an audio channel in parallel to the visual.
Hardware required (none specific)
Lyne's TV call display is a web page at /tv/{slug}. Runs on any device with a modern browser: smart TV with Chrome, older monitor connected to a computer, Chromebook, Mac mini, Raspberry Pi with Chromium. No proprietary LED display, dispenser, dedicated audio wiring, or physical totem required. Uses the monitor's audio for voice calls. On smart TVs without a proper browser, a Chromecast or HDMI cable from a computer is enough.
- Public screen at /tv/{slug} — any monitor with a modern browser
- Real-time updates via WebSocket, no refresh needed
- Synthesized voice (TTS) calls names and numbers out loud
- Auto fullscreen for continuous reception use
- No specific hardware beyond the monitor the business already has
Typical use cases by industry
At a medical clinic, the display shows patients waiting for consultations with Brazilian Law 10.048 priority highlighted, and the voice call replaces front-desk staff shouting names. At a notary office, it organizes queues by service (deeds, authentication, registration) with separate average times. At a restaurant, it shows table turnover and the next group to be called. At a public office, it ensures transparency by publicly displaying who's being served and how long each service takes.
Frequently asked questions about TV call displays
Do I need to buy a special TV or monitor?
No. Any monitor with a modern browser works — smart TV, older monitor with a computer, Chromecast in an older TV. Lyne uses only a web page at /tv/{slug}. The display cost is zero (assuming the business already has a monitor available).
Does voice call work in any browser?
Yes. Voice synthesis (TTS) uses the Web Speech API, supported in Chrome, Edge, Safari and other modern browsers. Audio comes through the monitor's or TV's speakers. On some devices you may need to allow autoplay in browser settings the first time.
How do I show multiple parallel queues on the same TV?
The display shows all the venue's active queues simultaneously, side by side, each with its own color (set per-queue). Useful for barbershops with multiple barbers, clinics with multiple offices, and labs with multiple collection rooms. In places with many queues, you can open multiple displays on separate monitors.
What happens when the internet goes down?
The TV display depends on connectivity for real-time updates. If the internet drops, the screen keeps the last known state and shows a "reconnecting" indicator. Operation resumes once the connection is restored. For businesses with chronically unstable internet, we recommend a 4G/5G backup link.
