Hey, looking into this myself. Wanting to tag company assets with barcodes for warranty and inventory purposes.

I found a Bluetooth enabled barcode reader that stores up to 4000 scans. You can scan and store or scan directly to an app on your BB through BlueTooth.

Free software for PC and/or Blackberry.

I can't post the link, but check out the Microvision ROV Barcode Scanner with Bluetooth on microvision.com

I am just starting the investigation, if anyone tries this, please let me know how it works for you.
