I doubt that this is possible.  In any case, a better solution would be 
to fix the barcodes in Koha.

Let me make sure I understand correctly: are you saying that the barcode 
in Koha is "112495d" but the barcode that you scan is "00112495d"?

Also, are you talking about item barcodes, patron barcodes, or both?

If you have access to your Koha server, you might be able to fix 
barcodes using SQL something like this (assuming you're talking about 
items):

    UPDATE items
    SET    barcode = concat("00", barcode)  -- prepend "00"
    WHERE  barcode LIKE "11_____"           -- five "_" characters
    ;

Please don't run this query as is!  Instead, use this is inspiration for 
a SQL query that fits your particular needs.  And check first -- for 
example, if you think most of your item barcodes are seven characters 
long, and begin with "11" or "12", see what numbers you get from a query 
like this:

    SELECT count(*), '11XXXXX'
    FROM   items
    WHERE  barcode LIKE "11_____"
    UNION ALL
    SELECT count(*), '12XXXXX'
    FROM   items
    WHERE  barcode LIKE "12_____"
    UNION ALL
    SELECT count(*), 'other'
    FROM   items
    WHERE  barcode NOT LIKE "11_____"
    AND    barcode NOT LIKE "12_____"
    ;

Good luck!

Paul.
