Queue Token Display & Caller (any TV or monitor, voice calls)

About the Queue Token Display & Caller (any TV or monitor, voice calls)

A token queue for a clinic, lab, shop, bank or office that runs in your browser. Give each visitor a token for a service (A-12 for Consultation, B-7 for Lab tests, or plain numbers), and let each counter, desk or doctor call the next one with a click or a number key. The display — this page on a TV or a second monitor — shows Now serving in large digits for every counter, flashes each new call, plays a chime and speaks the call with a voice of the device: English, Hindi or any other language the device has a voice for.

A slip with the token, the service, how many are waiting ahead and the time prints on a 58 or 80 mm thermal roll, through the print dialog or straight to an ESC/POS receipt printer. The Day report counts tokens, no-shows, waiting times and each counter’s work, and keeps the totals of the last 31 days. The queue stays in this browser, and you don’t need an account. In the free preview the display carries a “MySmartCoPilot preview” mark, and slips and reports show as marked page images; a Premium pass gives the clean display, slips and reports.

Common uses

• Clinics and OPDs calling patients to each doctor’s room, with names kept off the screen.
• Diagnostic labs and sample collection, with separate tokens for tests and reports.
• Banks, post offices, service centres and government counters with several desks.
• Restaurants and cafés showing which order is ready at the pick-up counter.
• Salons, pharmacies and shops where people wait their turn.

Putting the display on a TV

• Connect the TV or a second monitor to the computer that runs the queue (an HDMI cable is enough) and use it as an extended screen. Open the display in a new tab, drag the tab to the TV and press Full screen; the queue stays on your own screen.
• The control and the display talk through the browser itself (BroadcastChannel), so they must be tabs or windows of the same browser on the same computer. Casting the display tab from the browser to a TV stick works too, because the tab still runs on the computer.
• Calls are heard from the computer’s sound output: choose the TV (HDMI) there to hear them from the TV’s speakers.
• The display asks the browser to keep the screen awake (Screen Wake Lock) where the browser allows it; set the computer not to sleep as well.
• The buttons on the display fade away after a few seconds once the sound is on; move the mouse or press a key to see them again.

Voices, the chime and the wording

• Calls are spoken by the voices installed on the device. Set-up lists the languages and voices this device has, and Hear a call tries the wording. Windows, macOS and Android can add more voices in their speech settings (on Android: Settings → Accessibility → Text-to-speech output).
• Write what is said in What is said: {token} is read as its letters and then the number (A-012 becomes “A 12”), and {counter}, {service} and {name} are filled in. Use the wording of this language puts in a ready sentence for English or Hindi; for other languages, type it and name the counters in that language.
• Browsers let a page make sound only after someone presses something on it, so press Turn the sound on each time the display opens. Calls made close together are announced one after the other.
• A voice marked “(online)” is supplied by a remote speech service (localService), so its sentences go over the internet; the other voices speak on the device.

Slips and printers

• Through the print dialog: choose the thermal printer and the roll (58 or 80 mm) there; the slip is laid out at the roll’s own width.
• Receipt printer, direct (under Printing) sends ESC/POS commands from Chrome or Edge over Bluetooth Low Energy or a serial port (a USB printer that appears as a serial or COM port works through the serial port). Picture prints any script, including Hindi; Text is the quickest.
• Print a slip for every token given prints each new slip by itself: at once on a direct printer, or through the print dialog — Chrome started with the --kiosk-printing switch presses Print in that dialog by itself.

Waiting times and the day report

• The wait of a token runs from the moment it was given to its first call; the time at the counter runs from its latest call to the next call at that counter, or to Done.
• No-shows and tokens removed from the waiting list are counted apart and left out of the served figures. They stay under Missed or left: a person who comes back is called from there, and is then counted as served, with the wait up to the first call.
• Numbers start again at each service’s first number every day; earlier days keep their totals (tokens, served, no-shows, average wait) for 31 days. The CSV of the day lists every token with its times, counter and calls.

Names on a public screen

The name box is optional, and names stay off the display and the slips unless Show names is switched on. A waiting room screen is public, so many clinics show only numbers; switch names on only when the people agree to it.

Limitations

• The control and the display must be tabs or windows of the same browser on the same computer: a smart TV’s own browser, a phone or a second computer cannot follow the queue, because nothing goes through a server.
• Voices depend on the device: without a voice for the chosen language the call is not spoken (the chime and the screen still work).
• One queue per browser: up to 12 services, 24 counters and 3,000 tokens a day; earlier days keep only their totals, for 31 days.
• Direct printing needs Chrome or Edge and an ESC/POS printer over Bluetooth Low Energy or a serial port; other printers print through the print dialog.
• Clearing the browser’s site data deletes the queue and its history: download the day’s tokens as CSV when you need a record.

Privacy

The queue, the names and the settings stay in this browser on this device and are never uploaded; the display gets them from the other tabs of this browser, not over the internet. Calls are spoken by the device’s voices; a voice marked online sends its sentences to a remote speech service.
