+ it is generally possible to set up autopay for credit cards in the US, but it is not the default and I have never seen it not be very obvious on how to turn off. There's regulations about this in the US. + US debit cards and credit cards virtually all have chip and pin, but you can use only the number as a fallback for things like over-the-phone or Internet transactions, so it doesn't do much good. Terminals do usually require the chip, which presumably hinders skimming. AFAIK the old stamp machines are even still supported, though I haven't seen one in a while. + disputing charges on US cards generally consists of 1. login to the website 2. select the charge / hit the hamburger menu next to the charge 3. click dispute transaction.
