Arcade OS Program for payment of use in an Gaming Arcade

Anybody here know where I can get my hands on a program
that can be installed in a main pc computer network that my company can use as a cash register kind of thing
for a gaming Arcade?

My Gaming Arcade is currently using "tokens" that you put into Time Limit machines right next to the Xbox 360s, Wii and Ps3s,
but I am looking for a program that will bypass token use,
and the cash register can just simply load time and monitor use
for each console station. But our gaming stations
are primarily Xbox 360 Elites with HDTVs....

Like the ones they use at a net cafe, ya know what I mean?

Anyone who can help me,
I would be eternally grateful to.
And perhaps we can do business in the future.

Thanks!

BTW, this is Jav,
just posting this as a guest,
cause am too lazy to look for my pword....
lol....

Thanks to those who can help a brother out!
