Green Button or QR Code: Which Green Choice Solution Fits Your Hotel?

Both options let guests digitally opt in or out of room cleaning. But depending on hotel type, guest profile, and process needs, one solution is better suited.
Two solutions, one goal
Green Choice is an obvious step for many hotels: guests should be able to decide for themselves whether they want room cleaning or want to skip it. This avoids unnecessary cleanings, relieves housekeeping teams, and saves resources.
In practice, the question quickly arises: which solution fits your hotel better, the Green Button or the QR code? Both variants pursue the same goal. They make the guest's wish digitally visible and transmit the information to housekeeping. The difference lies mainly in operation, visibility in the room, and integration into daily hotel life.
The Green Button: the tactile main solution
The Green Button is a physical button in the hotel room. Guests press the button when they want to opt in or out of room cleaning. A green light confirms the choice directly in the room.
The big advantage is simplicity. Guests need no app, no login, and no personal smartphone. The decision is made right where it matters: in the room. That makes the Green Button especially low-threshold and intuitive.
For hotels, this is particularly interesting when Green Choice is meant to be permanently and visibly established in the room. The Green Button is especially well suited to city and business hotels with many recurring processes, larger properties with 50+ rooms, hotels with high housekeeping workloads, and properties with professional interfaces to PMS, hotelkit, or housekeeping lists.
The QR code: the lean digital alternative
The QR code is a simple solution without hardware. Guests scan a sticker in the room with their smartphone and make their choice digitally. This variant is especially suited to smaller hotels or properties that want to first test Green Choice without technical installation.
The downside: guests have to actively use their smartphone. As a result, usage can be lower than with a tactile solution directly in the room. The QR code is especially well suited to smaller hotels, pilot projects, and operations with simple opt-out logic.
Opt-in or opt-out: the model matters
Besides the technical solution, the operating model is also important. In the opt-out model, room cleaning is provided by default. Guests can actively opt out. Green Button customers achieve an average skip rate of around 40 percent here.
In the opt-in model, room cleaning is only carried out if guests actively request it. This makes savings of up to 70 percent possible, depending on hotel operations. The Green Button can represent both models especially clearly, since guests make their choice directly in the room and receive confirmation.
Which solution fits which hotel?
For larger hotels with operational housekeeping pressure, the Green Button is usually the stronger solution. It's visible, easy to operate, and provides clear digital signals. For smaller properties or initial tests, the QR code can be a sensible entry point.
What matters is not just the technical solution but the process behind it. The guest's choice needs to reliably reach housekeeping, otherwise no real added value is created.
Conclusion
The Green Button is the stronger main solution for hotels that want to permanently integrate Green Choice into their processes. The QR code is a lean alternative for smaller properties or a quick start. Both solutions can cut cleaning costs, save resources, and relieve housekeeping.
Frequently asked questions
Which is better: Green Button or QR code?
It depends on the hotel. Larger properties with operational housekeeping pressure usually benefit more from the Green Button, since it's visible in the room and works without a smartphone. The QR code is a lean alternative for smaller hotels or pilot projects.
What skip rate do Green Button customers achieve?
In the opt-out model, the average skip rate is around 40 percent. In the opt-in model, savings of up to 70 percent are possible depending on hotel operations.
Do I need an app for the QR code?
No. Guests scan the sticker in the room with their smartphone camera and make their choice on a web page. No app download or login is needed.
