Abstract: The present invention relates to a ticket management apparatus (TMA) for cashless operation of gaming machines (100a-100n), comprising a ticketing device (400a-400n) for inputting and outputting tickets (500) containing gaming data (502) and at least one data management device (101a-101n). The data management device (101a-101n) includes a gaming machine interface (GMIa-GMIn) for exchanging gaming data (502) with a controller (103a-103n) of a gaming machine (100a-100n), a ticketing device interface (TDIa-TDIn) for exchanging gaming data (502) with that ticketing device (400a-400n), a processor unit (106a-106n), a memory unit (107a-107n) and an external communication interface (ECIa-ECIn) for exchanging gaming data (502) with one or more devices (208) external to that ticket management apparatus (TMA).
