The chip is nearly 100% reliable (absent any manufacturing defects). It's the network in the U.S. that is stuck in the 1970s. Even with the supposed requirement to move to chip terminals, I still come across so many merchants who either (1) don't even have a chip reader, or (2) have a little sticky note on the payment terminal that says "chip broken". What's really surprising is when a new store opens (restaurant, typically), and they don't have a chip reader on day one. They still swipe. I've had my card skimmed more times than I can count over the decades. That we're still dealing with this problem in 2019 is maddening.
