What side of the body does a person wear their name tag on? (left or right)

Right side.

Explanation:

Although it is much easier for a right handed person to wear their name tag on the left side, it is actually correct to wear it on the right side as it is easier for the person shaking hands or greeting has easy eye contact with both the person and the badge.
