From the page:"Here's our official advice on signing the strip on the back: Don't sign it. It's useless as a deterrent, as anyone who takes your card then has a sample of your signature which they can not only use on any charge slip, but on your checks as well. However, do not leave the white strip blank. In that space, write: "Ask For Picture ID," and be prepared to back that up someday when you're in a hurry and the clerk wants to see a driver's license as well as the card. It makes the charge transaction a little longer, but a lot safer."

It really is a great tip.I am going to have a debit card soon(don't have any card right now).Will surely follow this tip.
