I am trying to add the 'Scan Card' capability to my STPAddCardViewController.
According to a few Google searches, all I was required to do was install the Card.io library alongside Stripe, however when I go ahead and present the STPAddCardViewController, I am not seeing the ability to scan a card:
STPAddCardViewController *addCardViewController = [[STPAddCardViewController alloc] init];
addCardViewController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addCardViewController];
[self presentViewController:navigationController animated:YES completion:nil];
Are the some specific customizations I'm missing to get Card.io integrated?
