-----------
freeware ..
Barcode/13 is a full software barcode scanner for palmOne Treo600 and palmOne Treo650. Barcode/13 uses the Treo camera to scan ISBN, UPC-A and EAN-13 barcodes and exports the decoded value to the system clipboard. Barcode/13 can be launched within any application, and the returned value can be retrieve from the clipboard to make use of it into the initial application.
Barcode/13 is a free alternative to expensive hardware solutions. Barcode/13 can't be seen as a business solution, but it is definitely the cheapest solution for non-business use, like cave, books, CDs or DVDs inventories.
