As far as I understood it is Barcode generation and not scanning.
I'm in a project using EAN13 (and 8) a lot, but the scanning is done at the client with a third party lib. However it is good to know I'll have support at the server side.
Regards,
Excellent
How do you plug that with a camera and image recognition system?
