A Point-Of-Sale (POS) processing environment is encapsulated within a container running on a first Operating System (OS) of a transaction terminal. Peripheral drivers for connected peripherals run on a second and different OS of the transaction terminal. A platform processing environment runs the peripheral drivers on the second and different OS of the terminal. A socket interface is provided for communication between transaction applications of the POS processing environment with the peripheral drivers of the platform processing environment for purposes of allowing the transaction applications to control and access the connected peripherals during transactions performed at the transaction terminal via the socket interface.
