dear all..i have made my project using Linux Ubuntu 9.04 OS.i want to use barcode scanner for my project.Can you tell me what's barcode scanner that compatible with this OS.?
Nearly all modern (last few years) barcode scanners that plug in via USB or PS/2 (e.g. NOT serial) are compatible with all operating systems.
When connected to a machine, they get detected as a standard keyboard. All the "magic" happens within the unit itself, so, you just point it to a barcode and it will input the numbers/characters/pattern in the exact place of the cursor, as if you typed them on a keyboard.
FYI - The only difference between new scanners is usually that some send a line return after processing and others don't, as well as speed of the unit.
