Customer-facing display

Show the ticket, totals and a thank-you screen on a second monitor facing the customer.

A customer-facing display is a second window of RKCoders POS. It sits on the monitor that points at the queue, not the cashier. It never opens the till, never asks for a PIN, and never shows cost or stock.

For a two-line COM pole on the counter, see Pole display. That hardware is configured on the same Settings page, in its own card.

What the customer sees

  • Idle. Your welcome line and optional promo images, rotating on a timer.
  • Sale. Ticket lines (with photos if you want them), VAT, discounts, the running total, and the amount already tendered.
  • Thank you. After the sale is saved, a short thank-you screen. If there is change, it is shown in large figures, then the display returns to welcome.

The newest line can be highlighted so the customer can confirm what just went on.

Turn it on

  1. Attach the second monitor in Windows and extend the desktop (do not duplicate).
  2. Open Settings → Customer display.
  3. Turn on Show customer display.
  4. Pick the customer monitor, or leave Second monitor so the till chooses the non-primary screen.
  5. Leave Full screen and Keep on top on for a shop floor.

The display opens with the till on the next start. You can also open a windowed Preview on this screen from Settings when you only have one monitor.

Language, theme and size

The customer screen can follow the till, or you can lock it to English or Arabic and to a dark or light theme. That is useful when the cashier works in English and the queue reads Arabic. Text size is independent of the till zoom.

Welcome, thank-you and promo slides

Write the welcome and thank-you lines in both languages. Choose a welcome image, then add extra promo slides if you want a short rotation while the till is idle. Tap a slide in Settings to remove it.

Thank-you duration and rotate interval are both in seconds.

If the display does not appear

  • In Windows, the second monitor must extend the desktop. Duplicating the screen will not give the till a separate surface.
  • Confirm Show customer display is on, then use Preview on this screen to prove the window itself works.
  • If the window opens on the cashier monitor, pick the customer display explicitly in Settings instead of leaving Second monitor.
  • Closing the till window also closes the customer screen. Open the till again and it will come back.

Closing it

Turn the setting off, or use Close display. Closing the operator window also closes the customer screen so it cannot be left up on its own.
