Methods for extensible device drivers and an extensible device driver Self-Service Terminal (SST) are provided. A SST includes an operating system (OS) having a communication port and an application having low-level commands that are specific to a hardware device, which is coupled to the SST; the low-level commands directly capable of being executed by the device. The communication port is operable to relay information and commands (including the low-level commands) between the device and the application. The application directly controls the device, with the low-level commands, and the low-level commands unrecognized by the OS.
