ABSTRACT:
An apparatus for reading a digital data word stored on a manually inserted card. The card includes a digital data word comprising a plurality of encoded characters stored on the card in the form of a two dimensional data matrix.
The card reader includes a linear array of row data detection elements and an array of one or more rows of column data detection elements, each row being disposed perpendicular to the array of row data detection elements. As a card is inserted into the reader, the column data detection elements detect and store the data bits for each of the characters from the rows of the data matrix as those rows pass the column data detection element array. A circuit means coupled to the row and column data detection arrays identifies the detected column data with the corresponding rows of the data matrix which are currently overlying the column data detection array. Following full insertion of the card into the reader, the complete data matrix may be read out from the card reader memory.
