[AccessD] Read picture of barcode

Hi all

Our postmen here will move from mobile scanner devices to the much cheaper standard smartphones.
These can snapshot a picture of the barcode on the delivered parcel and send it back at once to the mail office as part of a log.

But how do you "scan" a picture of a barcode to obtain the barcode?
I know some OCR applications can do that but I would prefer a small dedicated tool or ActiveX/OCR control.

Any experiences with this or ideas?
