ABSTRACT:
A method is provided for transmitting and/or receiving files via a facsimile machine or computer fax modem. Electronic binary files residing on a computer, for example executable files, word processing files, database files and other types of files are converted to a machine readable binary bitmap in the form of a black and white bar code. Preferably the converted file is encrypted before being transmitted and printed. A receiving computer fax modem or facsimile machine can then print the file for later retransmission or storage, or a computer fax modem can reconstruct the file so that it can be used and/or executed after being received.
