Let's just put this into perspective. While Australia is approximately the size of the continental U.S., the population of Australia is slightly less than the population of Texas. The U.S. Population is about 13 times more than that and has more than basically two centers of population (Perth and the Southeast coastline).On a trip to SF last year, I was paying for merchandise at Alcatraz. I was absolutley shocked when I had to insert my Visa Debit Card and had to sign for a purchase. We got rid of signatures in Australia back in 2014. I really don't understand how the US is so backwards on Card Technology when they are the home of MasterCard, Visa and AMEX.
