What is Point of Sale (POS)?
The retail till + payment + inventory system that processes the customer transaction at the moment of sale — integration target for self-service kiosks, queue platforms and customer-feedback loops.
Also known as
Point of Sale (POS) — explained.
A Point of Sale (POS) system is the retail estate's transaction-processing surface — the till that scans the basket, applies promotions, takes payment, prints the receipt, updates inventory, posts the sale to the back-office accounting system, and writes the customer record to the loyalty platform. In a self-service kiosk or queue-management context, POS is the integration target: a QSR order kiosk must place the order into the operator's POS so the kitchen-display system fires; a retail self-checkout must call the POS to apply the customer's loyalty discount + accept payment; a banking branch QMS must call the core banking system (the bank's equivalent of POS) so the teller's screen pre-loads the customer + the requested service. Major retail POS platforms in 2026 include the operator's existing till stack (Zeour does not name specific POS vendors as competitors — they're integration partners, not vendor competition). The integration is typically REST + webhook, sometimes a proprietary protocol via certified middleware. Per-vertical patterns vary: QSR + restaurant + retail self-checkout each call the POS differently. The procurement requirement is that the QMS / kiosk / queue platform speaks the operator's existing POS without forcing a POS replacement.
Why operators care about point of sale (pos).
POS integration is the gate between a self-service kiosk pilot and an estate-wide rollout. A kiosk that cannot place orders into the operator's existing POS is a demo, not a platform. Operators do not replace POS to deploy a kiosk — they require the kiosk to fit the existing till stack.
Buyer's checklist
- REST + webhook + (where required) certified middleware to the operator's POS
- Per-vertical patterns: QSR / restaurant / retail self-checkout each handled correctly
- Loyalty + promotion application at the kiosk level
- Inventory + stock-availability sync (so kiosks don't sell what the till can't fulfil)
- Settlement reconciliation against the POS daily report

Queue Management System
Queue & Customer FlowSoftware that issues tickets, segments visitors by reason of visit, routes them to the right counter, and measures the wait — across one branch or thousands.
Self-Service Kiosk
Queue & Customer FlowA touchscreen station — Android or Windows — that issues tickets, prints receipts, accepts ID scans, takes payments, and stands in for a staff counter.
Average Order Value (AOV)
Queue & Customer FlowThe mean revenue per transaction across an operator's retail or hospitality estate — primary metric for measuring kiosk upsell impact, drive-thru order optimisation, and basket-building campaigns.

Abandonment Rate
Queue & Customer FlowThe percentage of visitors who join a queue but leave before being served — a leading indicator of dissatisfaction and lost revenue.
Branch Transformation
Queue & Customer FlowThe end-to-end programme of rethinking what a physical branch does — usually replacing teller-heavy floors with advisory-led layouts powered by digital self-service, queueing, signage, and feedback.
Core Banking Integration
Queue & Customer FlowThe integration spec between a bank's queue management / appointment / kiosk platform and the bank's core banking system — Temenos, Finacle, Mambu — so customer + account data pre-loads at the counter.
