For more than a third of booked meetings, nobody shows up, and the room stays reserved anyway. Occupancy data from VergeSense puts the global share at 37% (VergeSense, 2023). Castit worked with iiyama on an answer for smaller offices: a Castit room booking app that runs on iiyama touch displays and is managed in the same platform as your digital signage.
A small display at the meeting room door shows the room's information, and anyone can book the room by scanning the QR code on the screen. The displays in reception and the hallway keep running your content from the same Castit account. This article explains how the partnership came about, how room booking is set up in three steps, what else Castit runs on an iiyama touch display, what is coming next for touch, and how resellers can sell it under their own name.
What is the Castit and iiyama partnership?
Castit and iiyama worked together to bring Castit's digital signage and room booking to iiyama touch displays. The first result is a room booking app for small and medium-sized businesses, built into the Castit digital signage platform.
It started with a question that came up in talks between the two companies: what can a touch display do for a customer beyond showing content? After several rounds, the answer was a booking app for the offices that enterprise workplace tools tend to skip. iiyama stayed closely involved during development, which is why both the signage playback and the touch applications are integrated with iiyama hardware.
That involvement matters more for an app like this than for plain playback. A signage display only has to play a schedule. A display at a meeting room door has to keep the app on screen all day and come back on its own after a power cut, because nobody wants to send a technician to a meeting room door. Building together with the manufacturer is how those details get sorted out on the real hardware instead of in the customer's office.
iiyama was founded in Japan in 1973, and its range today runs from desktop monitors to touchscreens and large-format signage displays. It is also a manufacturer that made time to take part in a software partner's development, which not every hardware company does. The hardware for this job was already there. The ProLite TW1025LASC-B3PNR, for example, is a 10.1-inch Android touch panel that takes power and data over a single Ethernet cable and has an RGB LED bar around the screen to show whether a room is available.
Why do smaller offices need room booking on a touch display?
Smaller offices have the same meeting room problems as large ones, with fewer rooms to absorb them and usually no dedicated tool. When a company has two meeting rooms, one room blocked by a meeting that never happens is half the capacity gone.
The pressure sits on small rooms in particular. Sensor data from XY Sense, reported by Bloomberg, found that meeting rooms for two or three people are 90% full on average, which puts them among the most used spaces in an office (Fortune, 2023). Those are the rooms people grab for a quick call without opening a calendar, so the calendar and the room drift apart during the day.
Most of the businesses dealing with this are not enterprises. The European Commission counts 34 million small and medium-sized enterprises in the EU (European Commission, 2026), and few of them have a facility manager or a workplace platform. Demand from that part of the market has been strong for a long time, and it comes down to an easy tool at a price that still makes sense for a three-room office.
Take a 30-person engineering firm with three meeting rooms. A client call runs long in one of them, and a recurring Monday meeting that was dropped months ago still blocks another. Two colleagues are standing in the hallway with a laptop. A display at each door shows what is booked and until when, and a free room can be booked on the spot by scanning the QR code on the screen.
How does room booking work in Castit?
Room booking is set up in three steps in the room booking app inside Castit: connect a calendar, choose what the display shows, and let people book by scanning a QR code.
- Connect a calendar. Open the room booking app in Castit and connect Microsoft Outlook or Google Workspace. The display then works from the calendar your team already uses, so there is no second schedule to maintain.
- Choose what to show, and where. Pick the screen and decide what appears on it: meeting room info, panel design and style, people and equipment info, language, and the booking slots, days, and times.
- Scan to book. The display shows a QR code. Someone who wants the room scans it and books.
Step two is where an office makes the display its own. Showing equipment info tells people which room has the large screen or the conference phone before they book it. Setting the booking slots, days, and times keeps a room from being reserved outside the hours you want it used.
The QR code keeps the step at the door short. The person books on their own phone, and the display stays readable for everyone else walking past.
What does Castit run on an iiyama touch display?
On iiyama hardware, Castit covers room booking at the door, signage on the larger displays, and interactive apps such as Power BI on touchscreens. All of it is managed from one Castit account.
| iiyama display | Where it usually hangs | What Castit runs on it |
| --- | --- | --- |
| Small touch panel | Next to the meeting room door | Room booking app: room info and booking by QR code |
| Large-format signage display | Reception, hallway, canteen | Digital signage: playlists, templates, scheduled content |
| Touch display | Team area, showroom, production floor | Interactive apps from the Castit app store, including Power BI |
Room booking at the door
The room panel answers the two questions people have when they walk up to a door: is the room free, and for how long? If it is free, they scan the QR code on the display and book it from their phone instead of walking back to a desk. Because the app is part of Castit, the panel is set up like any other digital signage screen in the account. The office manager who already updates the reception screen can look after the room panels too.
Signage on the same account
The larger iiyama displays keep doing what a digital signage display does best: welcome screens, company news, canteen menus, safety notices. Castit includes ready-made templates, and you can create and edit your own slides and animations in the platform. For a small office, the gain of using one digital signage solution for both jobs is practical. The person who changes the welcome slide for tomorrow's visitor does it in the same place where the meeting room panels are managed.
Power BI and other interactive apps
Room booking is the first touch app, and more are planned. Castit's Power BI app is now available for touchscreens, so a report on the wall can be explored by touch as well as displayed. That is relevant to a lot of offices, because Microsoft reports that more than 375,000 organizations and 30 million monthly active users rely on Power BI (Microsoft, 2025). A sales team can tap from the monthly total into one region during the Monday stand-up without anyone connecting a laptop. New interactive apps will appear in the Castit app store as they are released.
How do you know the panels are working?
Castit's built-in Health Monitor shows the status of your screens in real time, including uptime, system information, and proof of play. For room panels, this is more important than it is for a lobby screen. A lobby screen that goes dark is obvious to everyone who walks past. A door panel frozen on "available" while a meeting is going on inside sends people into the wrong room, and after two or three of those incidents staff stop trusting the panels. With the Health Monitor, the person responsible for the screens, or the reseller managing the account, can see that a device has a problem without walking the building.
What do iiyama resellers and partners get from this?
**Partners get a software product to sell with the iiyama hardware they already supply, under the Castit label or fully white-labeled. Margin comes from a shared revenue model or a fixed price, and Castit stays in the background.**
Hardware margin is earned once. Software is billed for as long as the screens are in use, so a room panel project that looks small on the first quote keeps paying. It also tends to grow, because an office that starts with three door panels often has a reception display to add, and later a touch display for dashboards. With white label, the customer logs in to a platform that carries your name and pays the price you set. Castit sums this up as "Your brand, your price, our business," and it describes the division of work accurately: you own the customer relationship, and Castit builds and runs the software.
There are two commercial models. With shared revenue, the subscription income is split between you and Castit. With the fixed price, you buy at a set rate and decide your own resale price. Castit has also spent the past months upgrading the platform with new features, so a demo is the fastest way to see what you would be selling and to go through the numbers for both models.
Give every screen a job
A display at the door can take room bookings. One in reception can welcome visitors, and a touchscreen on the work floor can open a live dashboard. Castit runs all of them from one platform, and it starts with a conversation: book a demo or contact us, tell us what you want your screens to do, and we will show you how to set it up.
Frequently asked questions
Does Castit work on iiyama displays?
Yes. Castit runs digital signage on iiyama displays and touch apps on iiyama touch displays. iiyama was closely involved in development, so both the signage playback and the touch applications are integrated with its hardware. Content, room panels, and device status are all managed from one Castit account.
What is a room booking app for a touch display?
It is software that runs on a touch display next to a meeting room door. The display shows the room's information and a QR code, and people scan the code to book the room on the spot. Castit's room booking app connects to Microsoft Outlook or Google Workspace, was developed with iiyama for small and medium-sized businesses, and is part of the Castit digital signage platform.
How do you set up room booking in Castit?
Open the room booking app in Castit and connect a Microsoft Outlook or Google Workspace calendar. Then choose the screen and what it shows, such as meeting room info, panel design, people and equipment info, language, and the booking slots, days, and times. The display then shows a QR code that people scan to book the room.
Can one platform handle both digital signage and room booking?
Yes. In Castit, the room booking app and the digital signage software share one platform. The same account manages meeting room panels, reception and hallway displays, templates, and the Health Monitor. For a small office, that means one tool to learn and one supplier to call when something needs attention.
Does Power BI work on touchscreens in Castit?
Yes. Castit's Power BI app is now available for touchscreens, so reports can be displayed and explored by touch on an iiyama touch display. Room booking was the first touch app to come out of the work with iiyama, and more interactive apps will be added to the Castit app store over time.
Can resellers sell Castit under their own brand?
Yes. Castit is sold under the Castit label or fully white-labeled, so the platform can carry the reseller's name. Partners earn through a shared revenue model or a fixed price and set their own price to the customer. Castit works behind the scenes, and a demo covers both models in detail.
