How to Integrate Your WiFi with Your POS System

18 August 2026

Free WiFi that switches on the moment a customer pays.
Picture this: a customer sits down at a restaurant, orders a meal, and pays at the till. The moment that payment is confirmed, their phone is already online on the restaurant's WiFi. No ad to watch. No data bundle to buy. No code to type in. It just works.

That's what we've just shipped for ISN Free WiFi tenants.
Here's how it works: a venue's own POS or till system connects to our platform through a simple API. The instant a sale completes, it tells us who to grant access to (just a phone number) and that guest is online, whether they're already sitting on the WiFi splash screen or haven't connected yet.
For restaurants, cafes, and retail spaces, this turns free WiFi into an actual extension of the customer experience instead of a separate hurdle guests have to clear. Buy a coffee, get online. No friction, no extra app, no extra step.

Under the hood it's built to be safe by design: every grant is tied to a unique transaction reference so a network retry can never accidentally double-grant data, and every integration key comes with its own daily limit to bound worst case exposure if a key were ever compromised.
This is one of three things we shipped this week, alongside a multi-location revenue and alerts view for operators running several branches, and a footfall report showing how many guests are new versus returning.

Small businesses shouldn't need an IT team to run great guest WiFi. That's the whole point.
