Whats this free encoder and decoder model download all about?
A. The download is made available free of charge (along with the code) as a model for developers and as a ‘sampler’, if you will, for users. What an encoder does is to take the data you enter (your numbers) and convert it into the bars and spaces of a barcode for you. A decoder is the software used by, say, a scanner to turn the bars and spaces of a barcode back into data.
