I have 20 desktop systems (window operating system) in my gaming zone. All systems are connected with each other and with my system (server). When a customer wants to start a game then i enter time for that customer on application which runs on my server system. For example: customer wants to play 2 hours. Then i want to enter customer information and max play time (2 hours).
After 2 hours when the time is complete, game should be pause or stop automatically. If customer wants to continue game then i enter one more hour against this customer. After entering one more hour game should be continue automatically. My software should calculate charges against total playing hours for this customer. How can I do? I am web developer please suggest me which technology should I use for to develop this application.
