One day I read an article about reading barcode using my webcam in Ubuntu 12.04 by a some software which I don't remember now.
Can anybody help?
What software could help me by reading a barcode using a webcam?
ZBar is a library for scanning and decoding bar codes from various sources
such as video streams, image files or raw intensity sensors.
It supports EAN,UPC, Code 128, Code 39 and Interleaved 2 of 5.
This package contains basic applications for decoding captured bar code images
and using a video4linux device (e.g. webcam) as a bar code scanner.
