Our story
It started on the court
It is 2004. At De Rhijenhof in The Hague, players book their court online, and the court lights switch on by themselves. This is the story of a club that was well ahead of its time, and how that idea grew into Eventlogic.

2004 · De Rhijenhof, The Hague
Booking without worries
It is 2004. At De Rhijenhof, a racket and fitness centre in The Hague, a new system is running: the Time Reservation System, TRS for short. Its goal is written in the brochure of the time: make booking simpler, for the player and for the facility.
TRS was made for anything you rent for a short time, such as a tennis or squash court. At the reception desk, one daily grid showed which court was taken when, with its own colour for bookings, contracts, training and competition. Everything appeared on screen instantly, so double bookings were no longer possible.
Entrepreneur Roland Ketel, still part of our team today, was there from the start. The Eventlogic name did not exist yet. The idea did.

The kiosk
The kiosk took over the evening shift
At the facility stood a booking kiosk with a touchscreen. It took over the evening shifts at the reception desk, which saved the club a considerable amount in staff costs.
Members identified themselves with their fingerprint. Anyone paying in cash could use the cash readers and change machines. Making a booking took around 15 to 30 seconds, and anyone who did not arrive in time saw the court released automatically for someone else.
The photo shows the kiosk in 2017, after the modernisation: with a card terminal beside the cash readers.

Online and on the go
Booking on a PDA, before the iPhone
Players no longer had to go past the desk. On the club website, they could see at once which court was free and book online. They could even do so on the go, on a PDA, before the days of the iPhone.
Online payment did not exist yet. To prevent phantom bookings, non-members confirmed their online booking by phone with an automated telephone system: a computer voice asked for the booking number and checked that the call came from the number they had entered.
The website also showed the condition of the outdoor courts. That saved phone calls asking whether the courts were dry.

Lights on
A booking that switches on the lights
The special part was behind the scenes. A relay circuit linked TRS to the equipment at the facility: the lighting switched on and off according to the bookings, timers followed along and the buzzer was controlled smartly from the bookings too. An electrician installed the circuits, on boards that could each control up to eight devices.
Looking back, De Rhijenhof was a smart club long before anyone called it that. In 2004, this laid the core of what we still do: a booking that sets something in motion in the building.
2016
A new TRS
More than ten years after the first version, we fully modernised TRS. Booking now simply happened in the browser: players chose squash or tennis, a day and a free court, clearly arranged by hall.
What was new: players could pay for their court straight away, online while booking or by debit card on the touchscreen at the facility.
The starting point of 2004 still stood: make booking simpler, for the player and for the facility.

Next
Farewell to the booking system
Booking itself increasingly moved to specialist software providers, including KNLTB Meet & Play. We stopped our own booking system.
What remained was the part that had been special from the start: the link with the building. That is where we grew, with lighting, access and control of the sports building, linked to the booking software clubs choose themselves.
2024 · Delft
An office that shows what is possible
Eventlogic is part of Reset, which has its origins in Delft in 1987. This brings our knowledge of sports clubs together with IT and building expertise.
Since 2024, we have worked from a building in Delft where IT and Smart Buildings come together. The office is a demonstration in itself: lighting, climate, access, alarm and audio work together.

Today
The question then, the work now
Where TRS switched lamps through relays in 2004, today we control lighting, access, climate and energy in the sports building, linked to the club's booking software.
The goal has stayed the same: make booking and playing simpler, for the player and for the club.

Frequently asked questions
About our story
How did Eventlogic start?
In 2004 with the Time Reservation System (TRS) at De Rhijenhof in The Hague: online booking, a booking kiosk and automatic lighting control. The Eventlogic name came later.
What was the Time Reservation System?
A booking system for anything rented for a short time, such as tennis and squash courts. It consisted of a booking program for the reception desk, a booking kiosk, online booking and an electronic circuit for the lighting and other equipment.
Why was TRS ahead of its time?
Players already booked online and on their PDA, before the iPhone existed. A booking kiosk with fingerprint check, cash readers and change machines took over the evening shifts at the desk. Lighting and the buzzer were controlled from the bookings, and the website showed the condition of the outdoor courts.
Does Eventlogic still make booking software?
No. After the renewed TRS of 2016, we stopped our own booking system. We now link to the booking software clubs choose themselves.
How are Eventlogic and Reset related?
Eventlogic is part of Reset, which has its origins in Delft in 1987. This brings knowledge of sports clubs together with IT and building expertise.
Where is Eventlogic based?
In Delft. Since 2024, we have worked from the Reset building.
