What is Elay OS?

One system. Every screen. Zero paper.

Elay OS is a real-time restaurant operating system that connects every surface — the cashier's iPad, the chef's kitchen screen, and the customer's phone — into a single live data layer.

point_of_sale

Cashier POS

Opens tables, fires orders, processes split-tender payments. The front-of-house brain.

soup_kitchen

Kitchen Display

Every fired ticket appears here in under 50ms. No paper slips, no missed orders.

Guest QR Menu

Guests order from their phone. Their cart syncs in real time with the POS.

Open arrow_forward
boltReal-time sync — under 50ms
When a cashier adds a dish on the POS, the ticket appears on the chef's screen in under 50 milliseconds. When the chef bumps it to READY, the waiter's phone buzzes and the POS highlights the table — all from a single database event.

The PIN Login System

Every terminal is locked. Every action is attributed.

How to log in

1

Dark PIN screen appears

You cannot skip it. Every terminal requires authentication before showing anything.
2

Tap your 4 digits

Large hardware-feel buttons — designed for greasy fingers on a busy shift.
3

Auto-submits on digit 4

No confirm button. Instant. Wrong PIN? The dots shake and clear automatically.
4

Role-specific terminal opens

A cashier sees the POS. A chef sees the KDS. The system routes by role.

Switching users mid-shift

1

Tap the lock icon

Top-right of any terminal, next to your name. Turns red on hover.
2

PIN screen returns instantly

Current session data is preserved — only the authenticated user changes.
3

Next person enters their PIN

All actions from this point are logged under the new user's identity.

Firing to the kitchen

send

Tap FIRE KITCHEN in the right sidebar

scheduleAlgorithmic Pacing — why some items show as HOLD
The system calculates the longest prep time in the order. Faster items (Garlic Naan — 4 min) are held back so they arrive simultaneously with slower dishes (Biryani — 25 min). HOLD items auto-promote at exactly the right moment — no chef action needed.

Processing payment

Tap Settle Ticket

Full-screen checkout modal opens.
2

Review the bill
