Most scanners are detected by the system as a keyboard. They inject the barcode as a sequence of keys correcponding to the decoded barcode, typically terminated by a Enter key.
Some scanners can be configured to insert a leading and trailing character to make distinction between barcode and keyboard entry easier. Read your barcode reader manual for the details.

Not in LCL, but there's a 3rd party package called SymScan (http://wiki.lazarus.freepascal.org/SymScan) (seems device specific)

I think that jshand2010 wanted to ask if there is a package or unit that converts a barcode in form of an image file to numbers or text, i.e. a software solution in Free Pascal.
Of course, most barcode scanners are recognized as keyboards, but obviously that wasn't what jshand2010 was searching for. Likewise, these Excel barcode add-ins create barcodes from numbers or strings, but the question was for the oppositve conversion.

(Note from the moderator: threads about barcodes seem to attract spammers that just post random links to C# barcode packages. We try to remove them as quick as possible. If you notice them, please report them)
