Offline POS system for festivals and events

Offline POS system that keeps working without internet — unlimited in time and revenue. Transactions processed locally, automatic sync once the network returns.

What is an offline POS system?

An offline POS system is a point-of-sale that processes and stores transactions locally on the device, without needing an internet connection. Orders, payments and stock movements continue during an outage; as soon as the connection returns, the system automatically syncs all data with the central environment.

The difference is how far that goes. Many POS systems offer an offline mode as a fallback, with limits on the number of transactions, the amount or the duration. Whizz-kit is built offline-first: offline is the default state, not the exception.

Why offline-first is essential at an event

A festival site is the toughest possible test for a network. Thousands of visitors load the same masts, temporary wifi drops in rain or crowds, and the peak at the bar coincides exactly with the peak on the network. A POS that needs internet simply stops.

Downtime at the bar is immediate lost revenue: a queue that stalls during the headliner never comes back. That is why Whizz-kit runs closed-loop and offline-first — bar sales continue, even during internet or power failure. That is our revenue guarantee.

Unlimited offline: no time or revenue cap

Whizz-kit works entirely without internet, unlimited in time and unlimited in revenue. A full weekend without a connection is no problem: every transaction is processed locally and stored safely on the device itself.

This applies to every payment method we support — tokens, Eventcards (RFID/NFC) and hybrid setups run closed-loop and are therefore offline by definition. Contactless card payments also keep working without a connection.

Automatic sync once the connection returns

As soon as connectivity is restored, the POS devices sync automatically with the dashboard. Nothing needs to be exported or merged by hand; revenue, payment methods, stock and recycling rates arrive in one place on their own.

That keeps your picture complete and accurate after an outage — per bar, per staff member and per day, including the reporting and settlement after your event.

Frequently asked questions

Does the POS really work fully without internet?

Yes. Whizz-kit is offline-first: transactions are processed and stored locally on the device. No internet connection is needed to keep selling, and there is no limit on time or revenue.

How long can the system stay offline?

Indefinitely. Even a multi-day festival without a connection is no problem. Once the network returns, everything syncs automatically.

Can I accept card payments offline?

Yes, contactless card payments keep working without a connection, including Apple Pay and Google Pay. Tokens and Eventcards run closed-loop and are independent of the network anyway.

What happens to my data during an outage?

Every transaction is stored locally and safely on the device. Nothing is lost; as soon as the connection returns the devices sync automatically with the dashboard.

How is this different from a POS with an offline mode?

An offline mode is usually a fallback with limits on transactions, amounts or duration. In an offline-first system, working without a network is the default the entire system is designed around.
