Abstract

PURPOSE: To prevent forgery and misuse of a card, by providing a coded conductive stripe on the magnetic card baseboard, and making it have a double check function.
CONSTITUTION: A conductive stripe 3 made of metallic foil is coded and is embedded on the magnetic card baseboard 1 which has formed a magnetic film 2 having a magnetic record reproducing function. In this case, resistance ratio of the baseboard 1 and the stripe 3 is made not less than 107. And thin sliding terminals T1 and T2 which keep sliding contact with the card are provided in the electric circuit for checking this card. Resulting from the foregoing, in case of checking, the card is transmitted so that both its ends 1A and 1B can contact the terminals T1 and T2. When the terminals T1 and T2 keep contact with the baseboard 1, current does not flow since resistance between both the terminals, is high and voltage is not set up between the output terminals 4 and 5. When they contact the stripe 3, a large current flows and a coded signal is output between the terminals 4 and 5. Accordingly, since the card is checked both magnetically and electrically, its forgery or misuse is made impossible.
