Read the doc and you will findout quickly, this is 100% copy of verifinger SDK. I bet this people bought a copy of source from verifinger and put their label in. Even the name, verifinger and GrFinger. Don't develop your app with this. Running a business from Brazil won't help: law will catch them. Thives............
