I create application and I must scan ISBN without add-on (EAN13) and with add-on (EAN13+2). I have MC3190. Scanner in other application read both versions ISBN. In my apps EAN-13 is not a problem, but I can't scan EAN13+2 - read only 13 chars. I use Symbol.barcode from EMDK 2.9.
So, what I must doing?
Sorry, those links are for EMDK for Android but you will find equivalent functionality in the EMDK for C/C#. Since docs for that are offline-only I can't provide a link I'm afraid.
