Basically, if you're traveling into a business building, then I don't see a reason for a face picture, I ask for a face picture just for security alone and just to see who I'm communicating with, I don't think that's anything harmful at all. Heck, even some guys send me their picture before I even ask. Now, if they say they don't feel comfortable sending, then I don't force them or ask them anymore. I say not a problem, then I just ask them to tell me about themselves. I like to get to know the client a little bit before they come to my door, or I go to their door. Again, I don't think there's anything harmful in that.
Also, getting to know the client makes them feel more comfortable as well as you, and I think that's a good thing.
But that is just my opinion, we all have them 😁
