Per the terms of the cardmember agreement that you agreed to, you are required to sign the back of the card. If you do not, you are not authorized to use the card for any transactions.

It's all very silly anyway given that online credit card transactions almost never require a signature.

Quite honestly though, once a thief has access to your card, you have other problems. If they're close enough to see it, they're likely close enough to duplicate it and leave you the card with you ever knowing.

If the signature is that concerning, then use one signature consistently for your credit card transactions that's unlike the one you use for anything else.

If you don't like that option, then you probably shouldn't be using credit cards currently offered.
