An input/output (I/O) device for use with a gaming machine includes a communication interface communicatively coupled to the gaming machine, a memory area, and a processor coupled to the communication interface and the memory area. The processor is configured to generate a code based at least in part on a unique machine identifier of the I/O device and store the code in the memory area. The processor is also configured to receive a verification request of the code from the gaming machine via the communication interface, and transmit a response message to the gaming machine via the communication interface, wherein the response includes a number of available credits available to a player. |
