A data storage module is adapted to be coupled to supply data to the controller of a printer without external electrical terminals. Light and magnetic fields are employed to transfer data, clock and power signals. The resulting module is sturdy and eliminates the possibility of unintended exposure of either the operator or the delicate module electronics to electrical potentials.
