unity android plugin

I want to integrate card.io Android OCR sdk in unity for reading credit card numbers. So, i have created a jar file to call the card scanning module. But its giving me run time error “Failure to intialize . Your Hardware doesn’t support this application,sorry!”. Has anbody worked on such thing ?

Yeah i have done it
,Hi, I have found the problem and solution for it. And yes i am able yo do it.
The problem is that card.io has open cv libraries in both 32 and 64 bit but unity have only 32 bit library.
So, in 64 bit 32 bit mobiles like s6 libraries are ignored.
And the solution is that u have to use ndk filter for 64 bit libraries in builld gradle.
