SHAPE Services, creators of apps like IM+, have released Barcode Finder for iPad, plus an iOS 4 compatibility and feature update for the previously iPhone-only version, Barcode Reader.

Both versions offer the ability to find the most up-to-date and detailed information for any product as quickly and efficiently as possible. Taking advantage of eBay, Amazon, and Google results plus thousands of online retailers, you’ll be certain to find the best price possible, and it’s also a great source of information. Supporting UPC, EAN-13 and EAN-8 labeling standards makes this an extremely versatile shopping, comparison and research tool. Save or email your findings for easy retrieval and later comparison.

Barcode Reader lets you use your iPhone 3GS or iPhone 4′s camera to effortlessly take a photo of a product’s barcode, while Barcode Finder lets you quickly enter a barcode number or product name using the iPad’s full-size key keyboard since it lacks a built-in camera.

Go grab the updated iPhone 3GS or later Barcode Reader for free, or get the iPad-specific version for only $1.99.
