amazon-barcodeOn Tuesday Amazon released its updated iPhone app with some new add ons. The new update had a nice new feature in it, the ability to scan barcodes. The new feature is only available for iPhone 4 or 3GS running iOS 4. The barcode scanner lets you scan the barcode of any product available at Amazon.

After the scan the app will display the product number and its details following which you can buy the product if its available on Amazon. The new app is available via the iTunes store. The store will provide you with an alternative app if you don’t run the specified iPhone 3GS or iPhone 4.

This is a great tool for Amazon and a way for users to compare prices on the fly. If you walked into a store and scanned a product to match with a cheaper one on Amazon, thats a sale for Amazon!
