It's not useless, it protects against what it protects. Like
dumpster-diving in the imprint days or if someone gets hold of all the
credit card numbers + expirations (+ names, maybe) from your
database. If you don't store CVVs (which is forbidden by contract)
they won't have CVVs and sites which require them won't accept
transactions. It's kind of like a PIN but yes too easily stolen.

A friend used to write "ASK FOR PHOTO ID" in the signature portion of
his credit cards and, I saw this, cashiers would look at it, look at
his signature as if they were comparing, and say OK thank you!
