Amazon already allows you to scan a barcode on a product to purchase it online with an iPhone app and now the company has launched a new way to compare and shop with a free iPhone app called Price Check. The app lets you scan a barcode, or take a picture of the product, or even simply say the product’s name to access product listings on Amazon’s site.

Many of us will be using this one often. Right now users can take a photo of the item and match the picture to books, DVDs, CDs and video games, though Amazon says that it will be adding more categories very soon. This should make Xmas shopping a breeze this year.
