Barcoder is a program (available for casio and nspire) that can get information of barcodes.
It's something simple but I think is nice (for geeks :P).

It currently supports the following types of bar codes:
►EAN/UCC-8
►UCC-12
►EAN/UCC-13
►EAN/UCC-14
From a barcode (of the above type) this program can "extract" the following information:
►Country*
►Manufacturer Code
►Item code
*Sometimes the country shown is not the country of origin of the product but the place where it is sold.
The idea is based on java application "barcoder" by blackstripstudios (http://blackstrip.ru/soft.php?softyp=java&lang=en&softid=2) for mobile phones. Currently this program contains all functions of the original program, except verification of valid/invalid barcodes.
