iPhone Developer's Journal

Last week I wrote an article pondering the benefits of using my iPhone to capture the bar code on grocery store products, using the integrated digital camera, and then have my iPhone use its GPS coordinates to look at the prices of this product in other grocery store locations that are close to mine.

In the comments part of that article, I received some good feedback from industry veterans identifying some of the challenges to accomplishing that dream. For example grocery stores don't want you shopping around for other products so don't publish their prices, and grocery stores don't want the food manufacturers promoting their products at other locations.

I did receive some links to software companies that are taking steps in that direction. Here is one link from Pic2Shop for your reference.
