Today, I received a new credit card which still needs to be signed in the little box on the back. I have never been able to do this successfully. A ballpoint pen won't write on the surface properly and leaves a miserly thin line. Most felt pens won't write on it at all. Those that DO write usually rub off after a short time. Most felt pens are FAR too fat to sign in the nano-scale box they provide. Any suggestions?
I sign with a Sharpie. Not a fine tip one either. It doesn't wear off and it's easy to read. Nobody has ever objected. We keep one around for writing on CDs and DVDs anyway.
Pens for labelling CDs/DVDs work very well for this. They won't wipe off and come in sizes of about 0.5 or 0.7 mm, around about that of a ballpoint pen.
Banks and financial institutions prefer the miserly thin line you dislike.
Forgers love thick lines that disguise small irregularities in a bogus signature. It's VERY difficult to forge a signature using a fine-lined writing instrument such as a ball-pointed pen.
Stop into a bank branch and use one of their pens next time you need to sign your John Bull. It won't cost you a pence and you're assured of using the proper tool.
Signature authentication is not there for legibility or aesthetics. It's there to spot differences and irregularities.
An engraver/Dremel. I just signed my new credit card with an engraver with a thin point, and it looks great and is visible (even without ink). I might use a thin sharpie to write over it.
A related suggestion for new cards - scratch out or Sharpie-over the three digit CVV code, which is at the end of the signature line. Make sure it is not visible. Do it for all of your cards. Then write (or engrave lightly) a simple numerical variation, which you can remember.
Subtract 100 from the CVV.
Actual CVV Re-written CVV 385 285 584 484 104 004
I've been doing this on all of my cards and it gives me piece of mind about online fraud, by hiding the CVV from others. Only 2-3 times in about 6 years has anyone (at restaurants - I think it was in a foreign country) asked for it. Otherwise I just use it when I need to make online purchases. I just used the engraver for this for the first time. Engravers are not expensive and useful for marking a lot of things. Comments/thoughts welcome, and thanks for letting me go off-topic.
Invest in the fisher brand of pens called "space pens". They truly live up to the hype, they write every time, on basically whatever surface you need to write on (within reason, obviously not concrete or some crazy surface). I just signed my new credit card with it 5 mins ago, it was like writing on paper and effortless. Worth the $!
'Sign' the Credit Card, using a Sharpie Ultra Fine Point ™ marker with the phrase "Please Ask for ID" This works well for me in three ways:
1) I know that whoever is running my Credit Card is paying attention to detail. 2) I don't unwilling expose my signature. 3) I have a chance to compliment the person for their protection of My credit, AND that of their business
There are other answers suggesting the kind of pen to use. To prevent it from rubbing off, EVER, put clear tape over your signature after you sign. :)
I lightly rubbed fine sandpaper over the strip and then signed it with a standard ball pen.
