500RFID Vibrating Countdown Wristband System for Time Based Attractions
Manage timed attractions with MH-CR03 RFID countdown wristbands, vibration reminders, Timer Setters and access control turnstiles. Suitable for trampoline parks, laser tag arenas, indoor playgrounds and activity centers.
Best For
Trampoline Parks: Assign each visitor a fixed jumping session and provide a personal reminder before the play time ends. The entrance and exit turnstiles can check whether the wristband is still valid.
Laser Tag Arenas: Set the duration for each game group and let players check their remaining time without leaving the activity area.
Indoor Playgrounds: Help children, parents and staff see the remaining session time directly from the wristband, reducing repeated time enquiries at the front desk.
Climbing and Adventure Centers: Assign access according to the selected activity area and play duration. Expired wristbands can be prevented from entering again.
Multi-Zone Activity Venues: Configure different activity areas with different access permissions or play durations according to the visitor’s selected package.

How the Complete System Works
1. Register the Wristband
Staff register the wristband UID in the system and assign the visitor's permitted activity area and play duration.
2. Set or Activate the Countdown
In the standard operating method, the countdown begins when staff write the time to the wristband. For customized projects, the countdown can be configured to start when the visitor scans at the entrance.
3. Check the Wristband at the Entrance
The entrance reader checks whether the wristband has been registered, whether access is still valid and whether the visitor is permitted to enter that activity area. When the conditions are met, the connected turnstile opens.
4. Display the Remaining Time
The visitor can press the display button to check the remaining play time. The LED ring provides an additional visual indication during the session.
5. Remind the Visitor
Five minutes before the session ends, the wristband displays a yellow LED indication and vibrates three times. When the countdown reaches zero, the selected expiry reminder program starts.
6. Apply Expiry and Re-entry Rules
An expired wristband can be prevented from entering again. The system can also apply repeat-entry rules according to the operating requirements of the venue.
7. Check at the Exit
The exit reader checks the current wristband status. For overtime sessions, the exit can be configured not to open automatically and the visitor can be referred to staff.
8. Collect Charge and Reuse
Staff collect the wristbands after use, reset the timer, update the access permission and recharge them when required before issuing them to the next visitors.
