Package available (software and hardware), that scans barcodes and automatically displays product description? - pos manufacturer

I've packed a basement full of computer retailing and ready for inventory purposes or eBay is very complicated, between one and provide a manually. I want a software / hardware package that can scan me the barcode on the packaging or the packaging, and then automatically creates a product description or manufacturer, etc. (I know that, do automatically half.com books and CDs, it must a general registration of products with bar codes) on the spot. I am not with the point of sale solutions are concerned, because I will upload all the products that are not in a brick and mortar institution.
Thank you for your time and attention.
