According to a post by Occipital via BigBoss, "RedLaser is the most advanced realtime barcode scanner for common barcodes (UPC/EAN) that works across all iPhones with no autofocus camera necessary.
RedLaser scans in realtime straight from the camera feed - no photo necessary, and returns prices from Google product search and links to Amazon. Weve also released an SDK that developers can use to enable barcode scanning in their own applications."
RedLaser Beta Features:

"We released RedLaser 2.0 on the App Store for $1.99 a few weeks ago, but that version is now out of date. Rather than sit around waiting for approval, we decided to make RedLaser Beta available on Cydia until the latest version is approved. We made it free to thank the Jailbreak community for the great experience we had when we launched ClearCam."
The version currently available on Cydia for free is almost 3 revisions more advanced than the one currently available on the App Store. You can download it from the BigBoss repository. You can find the older App Store version here.
