# Use Room display
> Understand how Room display app uses color indicators to show live room availability, enable ad-hoc QR code bookings, and use a check-in feature to automatically cancel abandoned room bookings
Room display helps customers see room availability at a glance, make instant bookings via QR code, and prevents abandoned bookings with a check-in feature.
## How room display availability indicators work
Room display signals room availability by tinting the background color of the tablet.
| **Tablet color** | **Explanation** |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| Green | The room is available for booking. The free time until the next booking is longer than the minimum booking duration set for this room. |
| Yellow | A meeting room will become available in less than 60 minutes. |
| Red | The room is unavailable for the next 60 minutes. |
The display also shows the current and upcoming bookings. Bookings include the full name of the booker, booking title, and time. This helps users understand when the room will be free.
Room display respects users' [privacy settings](/customer-management/manage-user-account). If a user selects "Administrators" for their "Booking title visibility", their booking title will not appear on the display.
## How users make ad-hoc bookings with a QR code
Room display shows a unique QR code for the room in the bottom-left corner of the screen.
By scanning the QR code, users are taken to the room’s booking calendar in the member web portal or mobile app, where they can book the room instantly.

## How abandoned booking protection works
To prevent no-shows, Room display supports a check-in feature for totally free rooms (with "Money" and "Credits" pricing disabled).
When a booking is made for a room, it is initially created in a "Tentative" status. The booking remains "Tentative" until the user checks in via Room display.
When [creating](/resource-management/set-up) or [editing](/resource-management/edit-a-resource) a free room in Spacebring, you can enable and configure "Check in" to prevent abandoned bookings:
* **Abandoned threshold** — defines in how much time after the booking start the booking is auto-removed if nobody checks in. If the threshold is reached without a check-in, the booking status automatically changes to "Canceled".
* **Early check in** — defines how much time before the booking start the `Check in` button appears and users can check in. Once a user arrives and checks in, the booking status automatically changes to "Confirmed."
Before the meeting, the `Check in` button appears on the room display based on the "Early check in" time you set (e.g., 10 minutes before the booking starts).
If the user taps `Check in`, the booking is confirmed, and a confirmation message appears on the screen.
If no check-in happens, after the "Abandoned threshold" time passes (e.g., 5 minutes after the booking starts), the booking is automatically removed from the calendar, freeing up the room for others.
