Abstract

This is a method of coding credit cards or the like so that the numeric information on the card can be read directly in binary-coded decimal form. The coding utilized resides within the same space allocated to the numeric OCR font and does not interfere with or otherwise impair the function of the font.

Credit Card

This is a method of coding credit cards or the like so that the numeric information on the card can be read directly in binary-coded decimal form. The coding utilized resides within the same space allocated to the numeric OCR font and does not interfere with or otherwise impair the function of the font.

The coding is implemented by debossing, for each numeric symbol to be coded, selected ones of four points for ten numerics. Since the points are debossed, they do not interfere with printing operations when the card is so used.

Reading is accomplished by placing the card face up on a matrix of elastic diaphragm switches in which each numeric position is provided with four switches positioned to correspond with the four possible coding positions. The switches are scanned by any conventional method for reading the code debossed on the card. The debossed points can be replaced by holes which can be read by conventional optical, pneumatic or electrical devices if desired.
