I need to select a barcode “type” that has the greatest likelihood of being read after the barcode image itself has degraded from being faxed multiple times. For example, our documents may be faxed up to four times, and with each successive fax, the barcode must be read. So, what is the most readable type.
Furthermore, I would love to have the ability to read up to 50 characters and upper/lowercase, however, it readability would be improved, I could get the barcodes down to numbers only, around 10 characters.
Finally, I would love some advice on optimal size for maximum readability. Too big takes up too much space, but at the same time, I can deal with a bigger size if readability is better without diminishing returns.
