A method for initiating a transaction at a self-service terminal, the self-service terminal including an interface device positioned on a housing and electrically coupled to the housing via a secure physical connection, the interface device being planar, the interface device having a front, the interface device having a back, opposite the front, that is lockably and removably docked to the housing, the self-service terminal including a plurality of media readers integrated into the interface device, the method comprising:
- displaying, on an encrypted touch-sensitive display integrated into the interface device and positioned on a front of the interface device, a plurality of prompts to initiate a transaction at the self-service terminal, the prompts providing instructions for causing physical media to be read at any one of the plurality of media readers to produce identification data;
- directing the identification data from the interface device, via the secure physical connection, to a processor positioned in the housing;
- and
- automatically communicating data corresponding to the identification data from the processor to a server to allow access to an account associated with the physical media.
