Same with paper signatures. A signature isn't supposed to rigidly identify you, it is supposed to provide evidence that you signed the document / agreed to the contract. It's a subtle distinction.

Having signatures match is just one straightforward kind of evidence that you agreed to the contract.

Then why the farce of matching your signature with the signature on the back of the credit card? Or if you don't sign the credit card, asking for an ID? It always makes me laugh when the high school student making minimum wage checks my signature. Do they all need to be certified signature experts before getting a job as a cashier?

Do people still check the signature? I haven't had one on any of my cards for at least five years nor do I sign receipts with my name; nobody has ever questioned me or asked for ID.

Me neither - in 10 years, only one girl in a mall validated my sig with the one on the card. It was in a huge outlet "village".

Alive and well in my home town, admittedly outside of the city.

Cashiers are not supposed to check that the signatures match, they are supposed to check that the card is signed. A credit card is not a valid form of payment unless it is signed on the back. "See ID" is not a valid signature BTW. Cashiers who see that are supposed to direct the cardholder to actually sign the card before charging it.

Yea, but they reduce to saying that someone was present and agreed to the contract. I've ordered things online, don't receive them, and the courier tells me it was delivered and signed for. I don't know who agreed. Nobody is going to investigate the curves on the signature.

I am curious though which biometrics will eventually replace the signature, especially with so many transactions online where I can spend thousands of dollars without signing anything.
