  You want to play a game on a Point of Sale machine: http://en.wikipedia.org/wiki/Point_of_saleShouldn't you be working rather then playing games at work?   ;  Depends on the kiosk, as the hardware will be specific to each type.For example, on a JAMMA arcade machine, the coin/bill/card acceptor is its own little machine which verifies that the coin/bill/card is acceptable and provides sufficient funds. Then, it sends a voltage to the coin-in pin on the standard JAMMA edge connector, which is read by the software basically as a button-press.On a kiosk with an embedded system, possibly PC-based, possibly not, the coin/bill/card acceptor is probably wired up via a serial connection or GPIO. For the former, you will have to interface with the device using its defined protocol, for which a library is likely provided by the vendor. For the latter, it may be as simple as detecting a voltage on a GPIO pin, or a multi-pin protocol may be present; in either event, a library providing access is probably supplied, but some low-level coding may be required if not.Step one is to see if the vendor of the coin/bill/card acceptor provides a library for interfacing the unit. Failing that, they should provide documentation on the protocol and you'll have to write your own code to communicate with the unit.
