As far as I'm aware, there's no "reliable" solution for WMobile developers. Generally, this is the purview of the cell providers. Most of the work done is for proprietary applications. If you think about it, you'll need to control the camera, spot store the image, then run it through the analysis routine to find the barcode. The i-Nigma (i-nigma.com) utility is only for selected phones - I didn't see the Mogul, and only for entering URL's.
Motorola is working on the technology, and from what I see just about have it. Check out the review on
our Barcode Font site. Its lengthy, but look at the "Camera" section. you'll see some pics there as well. The program controls the camera, and when the code scans, it acts like you just typed in the characters in the barcode using the keypad.
Let me know if you have any questions.
