I am generating 1D Barcodes for USPS's EAN-128. But I don't have a scanner to check the end result.
Is there a free tool where I can use to check the Raw Data of the barcode? E.g. with the Start, FNC1, End, Mod103 checksum, etc.
JustScanIt is a free app to download and use instantly, where you can also 1) set verbosity for greater detail, 2) use clipboard to paste the decoded data in other docs, and 3) find examples in the help section for using the built-in commercial grade barcode scanning API found in Windows (lots of symbologies included and added as new versions of Windows are released).
More than most, it also provides control of advanced camera focus capabilities for higher performing read rates.
