inventorying by barcode

[ulysses]

hey guys,
i'm in charge of inventorying some equiptment at work, and i was wondering if anyone can recommend a good barcode scanning software that'll allow me to build an inventory quickly (just scan serial numbers and go, no need to add names). i've tried a few so far (some were for inventorying movies) but none seem to read these barcodes since they're longer than regular ones and some of the lines are a bit thinner.

thank you,
