Abstract

Abstract A device for insuring authenticity of a credit card or the like having holes therein representing by their positions and size a particular identification number, such as part of a credit card holder''s account number, in which the card differentially sets slides to contact certain of a series of contacts connected in random coded manner to a second series of contacts. The latter contacts are selectively placed in electrical circuit with an authenticity indicating device by means of manually settable slides so that only when the latter slides are properly set in accordance with a coded number known only to the proper card holder, will a complete circuit be made to the indicating device.
