Physical Description

(1) Card reader: Large mainly beige coloured metal cabinet with a door in the front and two doors at the back (each with ventilation grids with fans). The front door has a window at the top left hand corner revealing a control panel. The front door is cut away on the top right hand side revealing part of the card moving mechanism, which includes a box with a large number of cards. The box has a window in it. The cards are shiny on one side and dull on the other. The top card only has a shiny yellow surface on one side and a dull black surface on the other. Opening the front door reveals electronic circuity and more of the card moving mechanism.

There are two pull-out modules (one above the other) at the back on the bottom left. (1a) Box of cards: Each card has a serated end in a pattern that probably identifies the card number.
