Q: How daoes works the barcodes reading's process?

A: By default, the application that manage the laser scanner and send the read code to the active window, is the "scand" demon. This program is configurable editing the /etc/scan.conf configuration file, or using the graphical utility Laser Settings.

Some custom programs can possibly manage laser's capabilities without using scand demon: it's possible to manage barcodes reading using the functions provided by the software development kit (SDK).

Q: How can I show the current scand demon's version?

A: In order to show the installed scand demon's version, the user must launch the command "logread | grep scand" (without quotes) in a console, then look for the version among the output strings generated by the command.
