And my point is that V1 technology for credit cards happened in the 1950s, V2 in the 1970s and by the time chip and pin came around, credit cards were hardly new technology anywhere in the western world.

Claiming that the US had too large of an install base for chip and pin to work would be like claiming the US had too large of a propeller air craft install base to adopt jet engines (also developed in Europe), but somehow the US managed that transition just fine. Americas failure to adopt chip and pin has nothing to do with legacy, and everything to do with US culture has a different relationship which money and how it’s spent.

In Europe people generally expect to be challenged when spending money using credit cards, and that’s always been true. So chip and PIN was always an easy to sell to consumers. In the US, people simply don’t expect to be challenged, and even get up upset when challenged, when using a credit card. So selling chip and PIN to consumers is much harder, especially when the US so happy to accept exploitative banking practices, and crazy high fraud rates.
