    High contrast barcodes (black on white) is best and highly recommended. Anything less than this is okay, but subject to the quality of the barcode reader in use. The same is true of barcode size and density. Keeping close to nominal size is best, like you see in the supermarket, smaller sizes are allowed, but again subject to the abilities of the barcode reader.
