A method and apparatus for processing data in a computer system from a keyboard wedged device and a keyboard hook device. The keyboard wedge converts the data into standard keyboard keystrokes for transmission over a keyboard line. The keyboard hook provides a window through which scanned data is detected. Scanned data is distinguished from typed data using a software data processing application. The software is configured to identify scanned data based on characteristics of the scanned data. Processing functions are next performed on the detected data according to the particular application being used.
