Canada already went through this. It started with the POS terminals, then gradually the cards were replaced with chip cards, then gradually the text on the terminal changed from "Swipe card" to "Swipe or Insert card".
From a consumer perspective, it was virtually painless. The biggest change is that credit card transactions now require a PIN (assuming a chip card and chip-enabled POS).
