Auto scan or manual capture in ID verification case

The case is to verify users' ID documents (ID, drivers licence, passport) via smartphone. The goal is to get a clear and sharp photo of their ID for this step.

We currently can do 2 options:

A. auto scan, which records a range of photos when they pointing the camera to their ID and the AI selects the best shot to verify, which takes half a sec.

B. we can do the traditional 1 button camera shot to capture the single shot. We add a confirm window asking whether the photo is clear and sharp. And then the photo is uploaded.

Should I use the auto scan or manual capture? What are the best practices?
