Hi Everybody I am an MCA student.
I want to know how does the bar code reaer works and How we can use it
in a poject where we can take input by reading the bar code and
display the information about the item.
like in malls they just read the barcode and all the info comes there?
Which tool to use?
I am a fresher and want to implement this in project.
Thank U

It sounds like you want to do a project involving barcodes, and you
don't know how barcodes work. Step 1 would be finding out how barcodes
work. http://en.wikipedia.org/wiki/Barcode

I have a more specific question: If I need to use a barcode scanner that
is connected to a Windows 2000 workstation through either a serial port
(RS 232) or a USB port, how can I read data from the device in Java 5?

In particular, am I right in thinking that there currently is no Windows
implementation for either the Java Communications 3.0 API or for the Java
USB API (JSR 80)?

I don't know about those specific APIs, but if you google for "java
USB", for example, it looks like there *are* projects and libraries out
there to facilitate accessing USB devices. Having not used any of them, I
can't comment much more than that.
