Usually, the owner of game club/Internet cafe rely on the cashier and there is no mechanism for him/her to know how long each computer was on. We offer the solution.
As in case of billiards, here you can specify gaming time for each computer. The software will turn off the appropriate monitor as soon as time's up. Finally a single receipt is printed out, where the drinks, dishes and duration are shown.
A controller device, which we install, disables the monitors (not the computer, because the sudden disconnection from the current is harmful for the computer) after the time specified is up. It is controlled from the cashier's computer and each "order", ie the time spent on the computer is visible in the software.
Therefore, the owner (or a manager) can controll compliance between real profit and the information stored in the software.
