Do you guys sign the back of your cards?

I never usually sign the back of my cards.. I actually used to write "CID" on the back of mine..but when I would pay at restaurants it would get annoying..should I sign the back of it?

I always do.  Some establishments will not accept your card without signature.

Yep. I always sign them even though it wears off in a couple of months.

I don't. I write "see photo ID". Cashiers used to never ask and I'd always mention it to them. In the last year or so I've noticed more often than not they'll ask.

Yes, I sign all my cards.
