Scanning Barcodes To Compare Products At Store

by Giuseppe Taibi on January 11, 2010

Yesterday I was at the supermarket trying to figure out which one of two rechargeable batteries to buy. So I tried to dig up some reviews for both products by using the awkward combination of RedLaser + Safari Home Screen as described in Create RedLaser Custom App in 60 Seconds!. Basically, I created an Home Screen on my iPhone that first launches RedLaser to scan the barcode of the product, then launches an Amazon.com query to look up the item on Amazon.com. The blame is on Amazon.com for not letting RedLaser (and any other developer in the world) integrate their web services with mobile apps :( . This experience made me think of a cool feature that I would like to see on the Verbela iPhone app: barcode-based feature comparison. Basically, I’d like to be able to scan two or more similar products and have the app display a feature-by-feature comparison table, including ratings and reviews. This would be a very useful feature for the many purchases where price is not the only differentiator.
