Rcash is a type of server money, its made of points. Primarily to avoid money hackers/cheaters.
You won't find it online, so my advice is script it yourself or just give up.

Edit: The name "rcash" first came from West-Side RPG, then when Coole made his AG server, he used the same. (Thats the link of WS and AG he talked about above).
