Offline-first restaurant POS
Take orders when the internet drops, push tickets to the kitchen in real time, and hand registers between cashiers in half a second.
Everything your floor needs during lunch and dinner service — counter, kitchen, floor map, and handhelds on one stack.
Orders route instantly over WebSockets. Color-coded timers and prep status keep the line aligned without paper tickets.
POS caches the menu in IndexedDB and queues orders locally. When the WAN returns, transactions sync back automatically.
Design seating layouts, track open checks, and keep servers and registers on the same live floor state.
Face login swaps register sessions without PINs during peak. Vectors only — no face photos stored.
Split served tables into 2–99 checks with live tax and tip recalculation on merchant and customer copies.
Route tickets by station and open cash drawers through the local Lightserve Agent on Linux mini PCs.
Slide the match score and switch personas to see how register unlock works against the 0.60 threshold.
Toggle an enrolled cashier versus an unauthorized guest.
Lower distance is a tighter match. Unlock threshold is locked at d ≤ 0.60.
Euclidean Distance: d = 0.42 ≤ 0.60 (Matched profile). Cashier logged in.
Tune header copy and print options — the thermal preview updates as you type.

A Rust/Axum service on your LAN talks to Svelte 5 clients over REST and WebSockets — not a high-latency SaaS hop for every keystroke.
Sales keep moving when the ISP blinks. Orders write to local queue storage, printers stay on the LAN, and batches sync when the WAN returns.
Enrollment captures landmarks in-browser and stores a 128-dimension float vector. No image templates. Webcam stream shuts off after scan.
