Occipital has released an update to its RedLaser barcode scanning application for the iPhone and fourth-generation iPod touch adding the ability to scan QR codes as well as several other improvements. RedLaser allows users to scan barcodes with their device’s built-in camera and perform searches via Google Product Search and other search engines. RedLaser 2.9 adds the ability to scan QR codes containing information such as URLs, contacts, calendar events and more and adds eBay and Half.com searches to provide additional results. The new version also adds high-resolution Retina Display support for the iPhone 4 and fourth-generation iPod touch, improves scanning speed on the iPhone 4 and allows users to activate the iPhone 4 LED light during scanning. RedLaser requires an iPhone or fourth-generation iPod touch running iOS 4.0 or later and is available from the App Store as a free download.
