Nametag Protocols

Q: If name tags/badges are used instead of a lanyard, do you know what side to pin it on?
A: The right side.

After some research, here is what I discovered:

Per the Etiquette Diva Emily Post: "Although it is easier for right handed people to put a name badge on the left side, they correctly are worn on the right side so the person shaking hands or greeting has easy eye contact with both the person and the badge as a way to help remember the name or to see where he/she is from, etc. This is the purpose of wearing the badges in the first place."

However, per Scott Ginsberg:

There isn't a single book on networking, meeting planning or interpersonal communication that doesn't say nametags should go on the right... [they] say you should wear your nametag on the right hand side so it is visible in the direct line with your handshake. For the most part, I agree. And so do most people. This is one of the few nametag protocols most people are familiar with.
On the other hand, the horizontal placement of your nametag should be dependent on the capacity in which you are wearing it. For example, if you work in a hotel, in retail, at a trade show or any other mobile environment where there are aisles, rows and hallways, consider the possibility of wearing your nametag on the left side of your chest so it is most visible to oncoming traffic. (If you live in a country where you walk on the right side of the path.)
Now, this is a debatable issue. But the bottom line about horizontal placement is this: it doesn't matter which side of your chest the nametag lays, as long as it's above your breastbone and readable from 10 feet away.

Who knew this was debatable? Please feel free to chime in!
