I am here is also looking for the solution of the back side of business card.
The back side would have list the item they are selling which i can search it in evernote.
it's really matter for someone like me.
though i know there is an app named "名片全能王" which has this kind of function.
I still want to use just one app.
By the way, is there any possibility can have a feature to create contact in google directly after scan the card?
