Also unrelated to the main thread topic but the US never did chip and pin correctly, they seem to have forgotten the pin..? Credit cards (and debit) in the UK both have pins and must be entered for every transaction. In the USA I've never seen a credit card with a pin but they have a chip, and my debit card rarely seems to ask for my pin even though it has one.
According to the banks, Americans can't handle remembering a pin. I wish Iw as joking.
Really fucked me last month in Europe when my card wouldnt work at the subway machines. And they advertise it as the perfect travel card!
