Google provided the barcode-recognition line-interpolation software as open
source for Android developers to build on. That explains why I have about 4
barcode-scanning apps on the G1.

Note that most common cellphone camera's haven't advanced enough to get
reliable resolution for barcodes, in particular the up-close macro-like
distances you would use a scanner at.  My old nokia, despite the 3 MP
camera, couldn't get focus up close.

In a year or two that should be different for the currently available
