The US doesn't have chip-and-pin, we have chip-and-sign.
Chip-and-pin provides effective two-factor authentication (something you have, something you know) while chip-and-sign is only single-factor authentication. There is no way to check signatures in real-time (or even at all, really).
- gagege 9y agoPretty much every store I go to, I use the chip and then enter my pin. I haven't had to sign in over a year. I'm in South Dakota. Edit: I just figured out why. My bank is apparently providing the chip and pin functionality.
- paulmd 9y agoLucky you. Not having the chip severely reduces security (it can no longer prevent card theft, only cloning). Frankly it also precludes the idea of a "duress pin" that calls the cops, which should be a thing if it isn't.
