Answer 1

Hi we recently had a product which required bar code scanning functionality, in the end after evaluating a lot options we went with zBar but it does not work on iPhone 3G it requires 3GS or above.

zBar is an open source SDK you can download it from sourceforge.

What we're doing right now is scanning bar codes using the zbar SDK & then calling upcdatabase.com API through xml-rpc to get the information about the product back.

And its working pretty well.

If you do not want to pay redlaser or others for SDK I would recommend using this approach. But of-course the downside is iphone 3G is not supported which I think does not represent many devices & also recently Apple has also dropped its support for its upgrades as iPhone 3G users will not be able to upgrade to iOS 4.3.

I actually own a 3G iphone & its very slow on iOS version 4.0 .
