I am developing a barcode reader application and wants to upload it for free on appstore. So I need a free OPEN SOURCE that helps in barcode reading through images sent from iPhone(including 3G).
I have seen several threads but the reference provided by them are all paid APIs.
Any help would be really appreciated.
