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 (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)
