Abstract: A fare device having modular architecture includes a display module that controls inputs and outputs of a display of the device, a fare media reader module that sends and receives data from a fare media and processes fare transactions conducted using the fare media as payment, and an external communications module that communicates external data with one or more remote devices. A controller controls operation of the modules. A carrier board includes one or more mountings with which to communicatively couple each respective module with the at least one controller and a common communications interface coupled between the one or more mountings and the at least one controller such that each of the modules is communicatively coupled with the at least one controller. The interface includes a single communications protocol and each module has a translation element that translates a native communications protocol of a corresponding module to protocol.
