The customer-facing display

Any tablet or spare screen becomes a customer display — customers watch their items ring up, see the exact total, and answer the tip question on their own screen instead of under the cashier's gaze.

Pairing

1. On the spare device, open /display in a browser.
2. On the register, tap Display in the header — it shows a 6-digit code.
3. Type the code on the display. Paired. It survives refreshes and reconnects on its own.

What the customer sees

• The cart, live, with line prices and the running total — nothing else from your register leaks over.
• When you take a card payment with a tip prompt, the tip options appear on their screen; their choice flows back to the register (validated against the amounts you offered).
• QR payments show the code big on their screen.
• A thank-you screen with their change after a cash sale.

Unpairing

Tap the display's corner menu → unpair, or just generate a new code from the register — a pairing code works once and expires in 90 seconds.
