Example: back in 2009 I got an American Express card with contactless technology. It was one of the transparent cards with the blue square in the middle so you could see it right inside the card. Problem was, no store had a terminal it could be used with. After a few years, Amex gave up on it and my new cards didn’t have it. Meanwhile the rest of the world is starting to roll it out. After a few more years (last 4-5 years) cards finally got contactless again, after the rest of the world had had it for years.
Europe tends to be a whiney nanny state, but lacking enforcement means companies can violate legal rights for years and then be very surprised when they get slapped with more and harsher enforcement. Facebook is learning this right now.
The US, meanwhile gets 'adequate protection' against fraud, credit scores, identity theft, frivolous lawsuits and binding arbitration. If you're unlucky, the US gov and corporate system will grind your life to pulp for no reason, and the powers that be won't even notice they did something
As an european, I vastly prefer what I got above the US system and avoid credit cards as an unsecure mess that gets your money stolen. But maybe that's just because I never learned to navigate the US system.
Clearly both systems can function and both have big holes.
A surprising amount of people also get away with spending the bank's money and never paying them back, which I suppose some people also see as a benefit. They probably do pay enough late fees, interest, etc. in their life that the bank comes out ahead anyway, but I know multiple people who simply didn't pay on a credit card - ever - and nothing happened to them, other than a few-years credit hit that didn't stop other companies from continuing to offer credit.
+ 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.
(Usually the store electronically submits the check at the time of sale...)
