Mobile Toilet Countdown

There is a countdown system in the mobile public toilets in Fuzhou, Fujian. It charges 10 yuan per use. After scanning the code for payment, the mobile phone interface displays the remaining usage time and starts the countdown, but users can continue to use the toilet after the time is up. Here is a detailed introduction:

Purpose of the countdown system
Operators set up the countdown system mainly for two considerations. On the one hand, it is to prevent long queues during peak usage periods of public toilets. Through the countdown, users can clearly know their remaining usage time, thus合理安排 (arranging their toilet visits reasonably) their toilet visits, improving the usage efficiency of public toilets, and reducing the problem of long waiting times caused by users' uncertainty about their usage duration. On the other hand, it is to avoid individuals occupying the toilet for an excessively long time. With limited public resources, long-term occupation of the toilet can affect the normal use of others. The countdown system can to some extent restrict users' behavior and ensure the reasonable allocation of public toilet resources.

Countdown and actual usage
Although the mobile phone interface starts the countdown after scanning the code for payment, users can still continue to use the toilet after the time is up. This is because the toilet is equipped with a manual lock on the inside. When the user locks the manual lock, people outside cannot open the toilet door, providing a guarantee for the user to continue using it. In addition, some reports mention that the "user notification" that pops up after scanning the code states "said 6 minutes, unlimited time", which further indicates that the countdown is more of a reminder and restraint mechanism rather than a strict restriction on usage duration.

Correlation between charging and the countdown
This mobile public toilet charges 10 yuan per use, and there is a certain correlation between the charging and the countdown system. Charging can be regarded as a cost compensation for using public toilet resources, while the countdown system regulates and manages usage behavior based on the charging. Through this method, operators can not only obtain certain economic benefits but also ensure the normal operation and fair use of public toilets.
