It is a general practice to wear the name tag above the pocket on the right side of the outermost garment, be it a shirt, blazer, or blouse. The important consideration here is that the person you are meeting or shaking hands with should be able to see your name clearly. So, wear it in such a way that person sees the name and the details quickly. However, some organizations may have certain rules for placement. So, you have to carry it that way only. However, carrying it on the right side is common.
