Disclosed herein are techniques for facilitating communication with a smart card in communication with a gaming machine. In some implementations, a smart card interaction device may be activated. A smart card interaction device coupled with an electronic gaming machine may be identified within an operating system running at the electronic gaming machine. The smart card interaction device may be capable of facilitating communication between the electronic gaming machine and a smart card in communication with the smart card interaction device. A communication protocol interface may be initiated within the operating system. The communication protocol interface may provide a mechanism for transmitting messages between the electronic gaming machine and devices in communication with the electronic gaming machine. A first message may be transmitted via the communication protocol interface between the smart card interaction device and a first host server via a network.
