Same here. Old enough to remember when your signature on a credit card receipt would be given a quick look to compare it to the scrawl on the back of the card. If this was still being done I’d probably fail 50% of the transactions I attempt.

Nobody has checked the back of my credit card for the presence of a signature in decades, let alone whether the signature matches. (I also haven't bothered to sign my credit card for this reason, but also because why would I want somebody to have my actual signature if my card is stolen?) These days my "signature" on a credit card purchase is usually a smiley face. Nobody has ever complained.

Yup, it’s been decades - I remember it happening with the carbon copy imprinting devices and it may have been more common in the US rural South where I was working at the time. The squiggles I fingerpaint on checkout screens now are my version of your smiley face.
