i'm really into this whole "code" thing with my name right now. i've done several different types in the past 195 names but i thought this was another really interesting one.
One of the most widely used symbologies, Code 39 can encode
messages using capitalized alpha characters, numbers 0 through 9 and seven
special characters. It has a flexible, variable-length format. Code 39 is used
by the Department of Defense and by the automotive industry, among others. Its
main drawback is that it takes up a lot of label space, sometimes causing
problems when there is a lot of data to be encoded.
