ZXing – a mobile barcode reader, a google project is publicly out now. I have been tracking barcodes in mobile for quite some time and am going to download ZXing and give it a try. I have always thought that a barcode reader should be open source with sustained support for it, with google getting behind it I think that would be gauranteed. Seems like ZXing supports 1D barcodes as well , will be interesting to see how that works. Also would be interesting to see how it compares with 3GVision reader , it is one of the best readers I have seen.
