How best to visualize an either/or choice between different types of actions

So I have a modal window with some tabs. On one of the tabs there is a single input field for an identification number. Now we are adding some new functionality which will let the user snap a photo of the id and input the number automatically instead of having to write it out.

I'm having some trouble figuring out how to position the input field and the button so that the user clearly understands it's an either/or choice.

Right now they are separated by a line with the input to the left and the button to the right and there is a short explanation of the functionality above each of them. It gets the message across but feels strange.

It's a sort of weird situation because the choice is between two very different actions - either input text or press a button to take a picture. Has anyone come across a more intuitive way of giving users a choice between two actions of a different type?
