You need to make a photopicture of your passport by your iOS or Android (or webcam) Software application?
But it is not easy to satisfy their photo picture requirements?
It's not that tricky though, if you are in the picture and you are the real owner of that ID what supposed to worry about? They don't have tricky system for the verification as they are a legit business so they won't do tricks for their customers. If someone finds out that they are doing something wrong and trick their clients would you think that they'll stay in the business? I don't know what makes you think that this is a very hard part of verification through coinbase.
