A software application that is installed in a commercially available processor, which application; identifies a keystroke data stream as derived from a code pattern, stores the pattern in system memory, validates the data stream, extracts user identified fields, adds prefixes and suffixes to the fields, and transmits identified fields to the processor operating system as a keystroke emulating data stream. The DOD UID code, and other similar codes, specifies a lead character or characters as a code identifier. When the application of this invention detects this code identifying lead character it directs the processor operating system to store the character and subsequent characters in the system memory rather than process them as entries from a keyboard. The application sets a timer as each character is received. As long as the timer does not time out, each successive character in the stream is treated as part of the code data until a code specified end of data character is detected.
