1. A key card system comprising:
- (a) a key card receiver having a jack with plural terminals including power-out terminals, power-in terminals and data terminals;
(b) a power source connected to the power-out terminal;
(c) a key card having first and second sides, power-in contacts and power-out contacts located on both sides, first connection means connecting the power-in contacts with the power-out contacts including means to connect them through a body of the card, a plurality of data contacts located on opposite sides of the card, a plurality of conductors located on opposite sides of the card and connecting the power-in contacts to the data contacts, the conductors on one side of the card being alternately looped, second connection means extending through the body of the card connecting distal ends of the looped conductors to conductors on an opposite side of the card in opposite sequential order thereby enabling the cord to be inserted into the receiver with either side up;
(d) means for interrupting selected conductors for producing a binary code of shorted and interrupted conductors on the data contacts;
(e) converting means connected to the data terminals for converting binary shorted or open data from the key card concurrently received on the data terminals to sequential data; and
,(f) signal output means connected to the converting means for carrying the sequential data to a remote location.

Abstract
A key card receiver is mounted in the cab of a truck. The driver inserts a card with a power-in contact shorted to several data output contacts. A power-out contact provides power to the receiver to operate three sequentially connected integrated circuits and another integrated circuit for pulsing the three serially connected circuits to convert concurrent binary data of shorted or open conductors on the driver card to a sequential data signal.
