From the developer: "CyberCafePro is designed for owners of Internet cafes or any other business that needs to control, charge for, and report on the use of computers for gaming or for Internet access. It is not intrusive to your system files but locks control of the computer except for programs you allow customers to run. You can easily customize all programs, buttons, backgrounds, colors, sounds, and rates for the client interface, as well as languages for both the server and the client software. Print tracking has been added, allowing you to charge for pages printed by customers. The server can be licensed to handle up to 200 or more client connections. Superfast HTML sales reports can be generated, viewed, exported, and printed from your favorite browser, and all employee activities and sales are logged to help protect your profits."
Note: This is the server software. You can download the client here. When unregistered, the server will end client sessions at 60-minute intervals. Also, four clients will be allowed to connect. In the registered program, more than 200 clients can be connected to the server depending on license purchased. Registration starts at $299 US.
