Anyone know where I can find a cheap wireless barcode scanner?
I am looking for a wireless barcode scanner/reader that can store scanned information as I would need to walk around a large building, and then can upload the information to a computer via USB or so. I saw 1 or 2 for over 500 and was wondering if there was anything like this for a cheaper price.

Best answer:

I would suggest ebay or craigslist.
