I created this Code 39 Barcode Scanner to scan computer generated Code 39 barcode images as practice.
Images may be dragged and dropped, pasted (CTRL+V), or selected with the file chooser. An example image is preloaded.
More information regarding Code 39 may be found here: https://en.wikipedia.org/wiki/Code_39
