A great new feature of the 2013 Unleashed Barcode Edition (D200+/Dx000 as well as D300s versions) is that in SingleID mode you can “type in” custom barcodes to either append to a previously scanned barcode, or as a new barcode. This is done by scanning special barcodes for each digit 0-9 or character A-Z. You can create these barcodes yourself using a code128 barcode font (or generator) and the code “X,T” replacing X with the character you want to “type”.
