Credit Card transactions are done with PIN and CHIP here, so no need for signature any more, But in the US I have been asked to produce ID, and I did without an argument.
I really cannot see what is the problem.
Simple. Personal experience here.
When I first went to Australia in 1995, I had 2 credit cards to my name; one with a $16,000 limit, the other with a $5000 limit. I didn't use the lower card for the most because of the interest rate, but definitely used the higher one because the interest rate was low, and that the exchange rate at the time would come roughly equal to the amount of interest I'd have to pay back. So, even push.
Anyway, I went to use the card for for a purchase, was asked for ID (at that time, Nebraska required signatures on their IDs), so I provided it. the merchant compared not only my photo, but signatures between the ID, the card, and the receipt I signed, and pointed out that I made the loops in my Ls a bit too wide and to be careful of that next time. It was weird for me to hear that, because no-one really even bothered in the US. She was looking at that because they were making sure the signatures were right or every close to matching because of fraud.
Fast forward 5 years. I'm in Las Vegas, got paid that day, and am getting gas/petrol, plus knew that I had roughly $8000 sitting in my bank account. I'm using my ATM/debit card. Go to fill my car, use my card, and come back with 'insufficient funds'. I try it again, same thing. "WTF" I'm thinking.. Luckily, I have enough cash on me to pay for it, and head home.
Turns out someone got hold of roughly 1000 credit card numbers, made fake cards, didn't sign them, and went on a shopping spree. $12,000 worth of office laser printers, dinner for 12, and a few other purchases in Simi Valley, California. all with me having the original card still in my hand. Even worse: none of the places asked for ID or to match signatures.
Took me 3 months to recover from that, as I had payments bouncing all over the place. From then on, I had put on the back of my cards "Ask for ID and check signature", until my bank finally put both on the front of the card. Now, I no longer have a problem.
But that is why you should check both, because while someone can easily put together a fake ID, if signatures don't match, someone is going to get busted.
BL.
