I was looking for an app for phones (iPhone, Android and SmartPhone - any or all) that would simply run in the background and place any scanned upc code digits into the currently active textbox.
I've Googled for quite a while and only found an Android app that actually replaces the keyboard of the phone.
It seems like it should be easy (I have many for PCs) but I haven't done any handheld programming since Windows CE days so I don't know if this is possible (can apps see other apps controls in these phones).
Has anyone ever come across an app like this?
use the iphone sdk from zbar and you can do it inside your app.
